Kira Bonder: What to Know About Steve Bing’s Daughter and Family

Kira Bonder became known to the public through one of Hollywood’s most unusual family stories. As Steve Bing’s daughter, she was at the center of a paternity dispute involving billionaire Kirk Kerkorian, her mother Lisa Bonder, and a highly unusual DNA investigation that eventually identified Bing as her biological father. Years later, Kira’s name returned to the headlines because of a major inheritance dispute involving the Bing family’s trusts.

Unlike many celebrity children, Kira has largely stayed away from the entertainment spotlight. Much of what is publicly known about her comes from court proceedings and established reporting rather than interviews, television appearances, or an active public career. That distinction is important because numerous websites have published speculative details about her age, profession, education, relationships, social media accounts, and wealth without providing reliable evidence.

Kira’s story is therefore less about celebrity lifestyle and more about family identity, complicated relationships, inheritance law, and the extraordinary circumstances surrounding her childhood. She is the daughter of former professional tennis player Lisa Bonder and film producer and businessman Steve Bing. She is also the maternal half-sister of Taylor Jennings Kreiss and the paternal half-sister of actor and model Damian Hurley.

Public sources are considerably stronger on Kira’s family history and legal disputes than on her present-day personal life. For that reason, specific claims about her current occupation, relationship status, net worth, or social-media activity should be treated carefully unless supported by a reliable primary or reputable journalistic source.

Who Is Kira Bonder?

Kira Bonder is the daughter of Lisa Bonder and the late American businessman and film producer Steve Bing. Her family background placed her in a remarkable intersection of professional tennis, Hollywood, real estate wealth, and one of the most unusual paternity disputes to receive national attention in the United States.

Her mother, Lisa Bonder, was a successful professional tennis player who reached a career-high singles ranking of No. 9 in the world in 1984. Bonder competed on the professional circuit and won multiple singles titles before eventually stepping away from competitive tennis. The Women’s Tennis Association’s official biography also records that she had children from her family relationships, including Taylor Jennings Kreiss.

Her biological father was Steve Bing, a businessman, film producer, writer, and philanthropist whose entertainment interests included projects such as The Polar Express and Beowulf. When Bing died in June 2020 at the age of 55, CBS Los Angeles identified Kira as his daughter and Damian Hurley as his son.

Kira’s public story, however, did not begin with Steve Bing’s career. It began with uncertainty over who her biological father was. That question eventually produced a legal battle involving Kirk Kerkorian and led investigators to use DNA evidence obtained from an extraordinarily unusual source.

Kira Bonder and Lisa Bonder

Lisa Bonder is central to understanding Kira’s early life. Before becoming known through the family dispute, Lisa had established herself as a professional tennis player. She competed on the WTA Tour and reached No. 9 in the world, giving her a significant career of her own rather than simply being known through her relationships with wealthy men. The official WTA biography records her professional achievements and family background.

Lisa had previously been married to Tom Kreiss, and they had a son named Taylor Jennings Kreiss. UCLA’s official athletic biography for Taylor identifies his full name, birth date, parents, and family relationship to Kira. It specifically states that Taylor’s mother is Lisa Bonder and that he has two sisters, Kira and Kallah.

This makes Taylor Jennings Kreiss an important part of Kira’s family story, although he is not her brother through Steve Bing. Taylor is her maternal half-brother through Lisa Bonder. That distinction is sometimes incorrectly reported on celebrity biography websites, where family relationships are mixed together or described inaccurately.

Lisa’s relationship history later became intertwined with Kira’s paternity case. When Kira was born in 1998, Kirk Kerkorian was initially regarded as her father. The question of biological paternity would eventually change that understanding and permanently connect Kira’s name to Steve Bing.

The Kirk Kerkorian Connection

Kirk Kerkorian was a billionaire businessman associated with the development of Las Vegas and major entertainment properties. He had a relationship with Lisa Bonder and later married her. Their marriage lasted only 28 days, a detail that became widely discussed because it occurred in the context of the complicated family situation surrounding Kira.

For a period, Kerkorian treated Kira as his daughter. The situation became legally complicated when a child-support dispute developed between Kerkorian and Lisa. In 2002, Lisa sought substantial monthly child support for Kira, with the case generating considerable media attention because of the amount involved and the identities of the people connected to it. The Los Angeles Times reported that the requested figure was $320,000 per month.

Kerkorian disputed the assumption that he was Kira’s biological father. According to contemporary reporting, investigators working on his behalf began looking into Steve Bing, who had previously been involved with Lisa. The investigation ultimately produced DNA evidence that changed the public understanding of Kira’s parentage.

The result was extraordinary: Kerkorian was not Kira’s biological father, while Steve Bing was. The case therefore moved from an ordinary celebrity child-support dispute into a much broader controversy involving privacy, DNA testing, private investigators, and the complicated question of who should financially support a child.

The Unusual DNA Test That Identified Steve Bing

The most unusual detail in Kira Bonder’s early story involves a piece of discarded dental floss. During the dispute over Kira’s parentage, investigators connected to Kerkorian sought biological material from Steve Bing. Contemporary reports said that dental floss was retrieved from Bing’s trash and used for DNA testing.

The story became so famous that TIME gave the episode the memorable heading “Another Reason Not to Floss.” Its 2002 report described how DNA testing based on material retrieved from Bing’s garbage was being used to establish whether Bing was Kira’s biological father. Bing responded with an invasion-of-privacy lawsuit against Kerkorian.

The Los Angeles Times also reported that the DNA evidence pointed to Bing as Kira’s biological father. The case subsequently settled, but the episode remained one of the strangest celebrity paternity stories of its era.

For Kira, the significance went far beyond the sensational headlines. The testing established a biological connection to Steve Bing that later became important again when Bing’s family inheritance was contested. What began as a child-support and paternity dispute eventually became part of a much larger story about the Bing family’s wealth.

Steve Bing and His Relationship With Kira

Steve Bing was a complicated and highly successful figure in entertainment and business. He worked as a film producer and writer and was involved in financing several prominent movies. CBS Los Angeles noted his work on Kangaroo Jack, The Polar Express, Beowulf, and other projects. He also became known for philanthropy and political donations.

Kira’s relationship with Bing appears to have been complicated. Later reporting about Bing’s final years described a strained family situation and suggested that his relationship with his children was not straightforward. A detailed Los Angeles Times account reported that Bing had eventually fought on behalf of Kira and Damian when his father attempted to exclude them from a family trust.

That detail is particularly important because it complicates the simplistic descriptions found on some websites that portray Kira as merely a wealthy celebrity child. Bing’s own position in the inheritance dispute indicated that he wanted his children to have rights under the family trust, even though his relationships with them were reportedly complicated.

Bing died in June 2020. CBS reported that he was survived by Kira and Damian Hurley. His death immediately brought renewed attention to the question of what would happen to the family’s considerable wealth and to the legal dispute involving his father’s trust.

Kira Bonder and Damian Hurley

Kira Bonder and Damian Hurley are paternal half-siblings. They share the same biological father, Steve Bing, but have different mothers. Kira’s mother is Lisa Bonder, while Damian’s mother is British actress and model Elizabeth Hurley. CBS identified both children as Bing’s surviving children after his death.

Damian was born after Bing’s relationship with Elizabeth Hurley. Their own paternity story also attracted considerable media coverage because Bing initially disputed whether he was Damian’s father. A paternity test later confirmed that Bing was Damian’s biological father. This meant that Kira and Damian, despite coming from different relationships, were connected through Steve Bing.

Their connection became particularly significant after Steve Bing’s death because both were involved in the dispute over the Bing family trusts. Their legal circumstances were remarkably similar: both were biological children of Steve Bing, both had been born outside marriage, and both became central to a dispute over whether Peter Bing’s trusts covered grandchildren born under those circumstances.

The story of Kira and Damian therefore became much larger than the personal lives of two siblings. It became a legal debate about how a wealthy family had defined the word “grandchildren” decades earlier and whether those definitions could exclude biological descendants.

Taylor Jennings Kreiss and Kira Bonder

Taylor Jennings Kreiss is another important name when discussing Kira’s family, but his relationship to her is often incorrectly described online. Taylor is Kira’s maternal half-brother, not her paternal half-brother. His father is Tom Kreiss, while his mother is Lisa Bonder.

The UCLA Bruins’ official biography provides unusually useful family information about Taylor. It identifies him as Taylor Jennings Kreiss, records his birth on February 8, 1989, and states that his parents were Tom and Lisa Kreiss. The same profile says he had two sisters, Kira and Kallah.

Taylor also had a connection to UCLA through tennis. His official UCLA profile describes his high-school tennis background and notes that both of his parents played tennis. His father was a former UCLA player, while Lisa Bonder had a successful professional tennis career.

This family detail gives Kira’s background another dimension. Although her name is generally associated with Steve Bing and the inheritance controversy, she also comes from a family with a significant tennis connection through her mother and maternal relatives.

The Bing Family Trust Battle

Kira’s name returned to the headlines years after the paternity case because of a major dispute over the Bing family trust. Peter Bing, Steve Bing’s father, had established trusts intended to benefit his grandchildren. The dispute eventually centered on whether Kira and Damian qualified as beneficiaries.

The argument was based on the wording of the trust and the circumstances surrounding the children’s births. Peter Bing’s position was that the trust language excluded certain grandchildren born outside marriage unless they met additional conditions relating to living as members of the household of their natural parent. Legal reporting described the dispute as a battle over whether Kira and Damian should benefit from the trusts.

In 2019, Steve Bing successfully opposed his father’s attempt to exclude his children from the trust. A later appellate decision, however, reversed the earlier outcome. Reporting in 2021 stated that Kira and Damian ultimately lost the inheritance battle concerning Peter Bing’s trusts.

The case is significant beyond celebrity gossip because it illustrates how the wording of an estate-planning document can have enormous consequences. A biological relationship does not necessarily answer every question about trust beneficiaries. The exact language used when a trust is created, along with the law governing it, can determine who ultimately receives assets.

Why Kira Bonder’s Net Worth Is Difficult to Verify

Searches for Kira Bonder frequently produce claims about her net worth. Some websites publish specific figures, but there is no strong public financial record establishing a reliable current net worth for Kira.

This is particularly important because Kira has been associated with two very wealthy families. Steve Bing inherited a large fortune from his grandfather and later became involved in entertainment, real estate, and philanthropy. Peter Bing’s family trusts were also reportedly worth hundreds of millions of dollars. Those facts, however, do not mean Kira personally inherited a specific amount.

The inheritance dispute makes the situation even more complicated. Reporting about Kira and Damian concerned their eligibility for particular family trusts, not a simple calculation of Kira’s personal wealth. As a result, assigning a current dollar figure to her net worth without documentation would be speculative.

For a trustworthy biography, it is better to say that Kira Bonder’s current net worth is not publicly verified. Her connection to wealthy families is well documented, but her personal assets, income, investments, and current financial arrangements are not publicly established by reliable sources.

Kira Bonder’s Age and Birth Information

Kira was born in 1998, and contemporary reporting identifies March 9, 1998, as her birth date. An Irish Independent report from the period of the original controversy stated that Kira was born on March 9, 1998.

That date is more useful than relying on celebrity biography websites that sometimes give conflicting years. Some online profiles have incorrectly listed Kira as being born in 1999 or have repeated different ages without explaining their source.

Because Kira has maintained a relatively private public profile, there is no reason to assume that every personal detail published online is accurate. Her birth year and family relationships are better supported by contemporary reporting and official or legal records than many of the personal details found on biography websites.

As of 2026, a person born on March 9, 1998, would be 28 years old. Her age, however, is only one small part of a story that has been shaped far more strongly by her family’s legal history than by her own public career.

Did Kira Bonder Inherit Steve Bing’s Fortune?

This is one of the most complicated questions surrounding Kira. It is tempting to assume that being Steve Bing’s biological daughter automatically meant that she inherited his fortune, but the public record does not support such a simple conclusion.

Steve Bing’s children were at the center of an inheritance controversy even before his death. His father, Peter Bing, had challenged their status as beneficiaries of family trusts, and Steve Bing had opposed the attempt to exclude them. A 2019 ruling initially favored the children, but an appeal later changed the outcome.

There is also a distinction between Steve Bing’s own estate and the separate trusts established by his father. Articles sometimes blend the two together, creating the impression that one court decision determined the fate of the entire Bing fortune. In reality, the legal history was more complicated.

For that reason, claims that Kira simply “inherited nothing” or “inherited hundreds of millions” should be treated cautiously unless the claim specifies which estate or trust it refers to. The public reporting clearly establishes the inheritance dispute, but it does not provide a straightforward, verified figure for Kira’s present personal wealth.

Kira Bonder’s Life Away From the Spotlight

One of the most notable things about Kira Bonder is how little reliable information exists about her current day-to-day life. Unlike Damian Hurley, who has pursued a public career in modeling and acting, Kira has not developed the same level of entertainment-industry visibility.

This difference matters when evaluating online biographies. Search results can make Kira appear to be a highly public celebrity because her name is connected to Steve Bing, Kirk Kerkorian, Lisa Bonder, and the Bing inheritance case. But the quantity of information about a person’s family history does not necessarily reflect how publicly active that person is.

There are also online claims describing Kira as an equestrian or giving detailed information about her education, relationships, Instagram account, and career. Without strong primary or reputable journalistic sources, those claims should not be presented as established facts.

The most defensible description is therefore straightforward: Kira Bonder is a private American woman whose public recognition comes primarily from her family connections and two major legal stories, the paternity dispute surrounding her birth and the later Bing family trust litigation.

What Makes Kira Bonder’s Story Unusual?

Kira’s story stands out because several unrelated elements of wealth, celebrity, law, and family history came together around one person. Her biological father was a wealthy Hollywood producer, her mother was a former world-ranked professional tennis player, and the man initially believed to be her father was one of the most powerful figures in Las Vegas.

The paternity investigation was itself extraordinary. DNA was obtained from discarded dental floss, and the resulting evidence was used in a dispute that eventually identified Steve Bing as Kira’s biological father. The episode was also connected to the activities of private investigator Anthony Pellicano, whose later criminal case became one of the most notorious scandals involving Hollywood’s private-investigation world.

Then, almost two decades later, Kira’s name appeared in another major legal controversy. This time, the issue was not who her father was but whether she qualified as a beneficiary of a family trust created by her paternal grandfather.

That unusual progression explains why Kira’s name continues to appear in searches even though she has largely remained outside the public entertainment world. Her story illustrates how a person’s identity and family relationships can become legally significant long after the original events have passed.

The Lasting Legacy of Kira Bonder’s Family Story

Kira Bonder’s public story is ultimately a story about identity. As a child, the question was who her biological father was. As an adult, the question became whether her biological relationship to the Bing family was enough to establish inheritance rights.

Her relationship to Steve Bing is now firmly established in reputable reporting. CBS identified her as Bing’s daughter following his death, while historical reporting documented the DNA evidence that established Bing as her biological father.

Her family connections also extend beyond Steve Bing. Through Lisa Bonder, she is connected to Taylor Jennings Kreiss, whose official UCLA biography confirms that Kira is one of his sisters. Through Steve Bing, she is the paternal half-sister of Damian Hurley.

What remains less clear is Kira’s private life today. There is insufficient reliable public information to confidently describe her current career, relationship status, social-media presence, or personal fortune. A responsible biography should acknowledge those gaps rather than fill them with assumptions.

Conclusion

Kira Bonder’s life has been shaped by an extraordinary family history, even though she herself has largely remained outside the spotlight. Born to former professional tennis player Lisa Bonder, Kira was initially associated with billionaire Kirk Kerkorian before DNA evidence established Steve Bing as her biological father. The unusual investigation involving discarded dental floss became one of the most memorable celebrity paternity cases of its time.

Her connection to Steve Bing later became important again when she and her paternal half-brother Damian Hurley were involved in the Bing family trust dispute. Although an initial court ruling favored them, a later appeal resulted in them being excluded from the disputed trusts.

Kira’s family story also includes her maternal half-brother Taylor Jennings Kreiss, whose official UCLA profile confirms the connection. That detail is often reported incorrectly online, making it especially important to distinguish Kira’s maternal family from her paternal relationship with Damian Hurley.

Today, Kira Bonder remains a relatively private figure. The most reliable information about her concerns her parentage, family relationships, and legal history, while many details about her present career, finances, and personal life remain unverified. That makes a fact-focused approach more useful than repeating unsupported celebrity-profile claims.
