Kevin Costner’s Family: Where Cayden Fits In
Kevin Costner has seven children from three relationships, and Cayden sits in the middle of that lineage.
- Annie, Lily and Joe Costner are Kevin’s children with his first wife, Cindy Silva.
- Liam Costner is his son from a relationship with Bridget Rooney.
- Cayden, Hayes and Grace Costner are his children with Christine Baumgartner, with Cayden being the eldest of the three.
This large blended family has occasionally appeared together at public events, including film premieres, showing that the Costner siblings maintain close ties despite their parents’ separate paths.
Cayden’s Parents: Kevin Costner and Christine Baumgartner
Kevin Costner is an Academy Award winning actor and director, best known for films such as Dances with Wolves, The Bodyguard, The Untouchables, Field of Dreams and, more recently, the Horizon: An American Saga series and the television drama Yellowstone. Christine Baumgartner previously worked as a handbag designer and model before marrying Costner.
Kevin and Christine separated in May 2023, and their divorce reached a settlement in February 2024 after a widely reported legal process. Despite the split, both parents have continued to appear at significant moments in Cayden’s life, including his high school graduation.
Growing Up Away From the Spotlight
Unlike some children of famous parents, Cayden has largely been shielded from media attention throughout his childhood and teenage years. Kevin Costner has spoken openly about wanting his children to pursue their own interests without pressure from his own career achievements.

That said, Cayden has occasionally stepped into public view alongside his father. In 2024, at the age of 17, he accompanied Kevin Costner to the Venice International Film Festival for the premiere of Horizon: An American Saga – Chapter 2, where photographers noted how much taller he had grown than his 6ft1in father.
Cayden and the Venice Film Festival Appearance
What happened at the Venice Film Festival?
Cayden joined his father on the red carpet in Venice for the premiere of Kevin Costner’s self-written and directed film. Speaking about the experience afterwards, Kevin Costner described the four days they spent together as meaningful, noting that Cayden had watched him labour over the project for years.
The appearance offered a rare glimpse of the father-son bond, with Kevin using the trip as an opportunity to teach Cayden about perseverance and not giving up on long-held ambitions, lessons drawn directly from the decades it took to bring the Horizon saga to the screen.
Cayden’s High School Graduation
Did Cayden Costner graduate from high school?
Yes. Cayden graduated from a high school in Santa Barbara, California, with both of his parents attending separately to celebrate the milestone. His siblings Hayes and Grace were also present, alongside his half-sister Lily.
The graduation marked a significant moment for the Costner family, coming roughly a year after Kevin and Christine finalised their divorce. Photographs from the event showed a relaxed and supportive atmosphere, with both parents posing individually with Cayden in celebration of his achievement.
What Does Cayden Costner Do Now?
As Cayden has only recently finished secondary education, no confirmed career path or profession has been publicly announced. His parents have kept details about his further education and future plans private, consistent with their broader approach to shielding their children from unnecessary scrutiny.
Given his age and his family’s preference for privacy, it is likely that further updates about his life will emerge gradually, particularly if he attends university or takes on a public role in the future.
Conclusion
Cayden Wyatt Costner is the eldest son of Kevin Costner and Christine Baumgartner, born in 2007 and raised largely away from public attention despite his father’s fame. He has made occasional public appearances, most notably at the Venice Film Festival and his own high school graduation, both of which highlighted a strong bond with his parents even after their divorce. As one of seven Costner siblings, Cayden represents a new generation of the family whose future path remains largely private for now.
