Cayden Wyatt Costner was born on May 6, 2007, in Los Angeles, California. He is the eldest son of Kevin Costner and Christine Baumgartner. From the start, his name attracted attention because of his famous father.

Many people know Kevin Costner from movies like The Bodyguard, Dances with Wolves, and the hit TV show Yellowstone. But to Cayden, Kevin is simply “Dad.” Even though his father is one of Hollywood’s most respected actors, Cayden has not lived a flashy public life.

As of 2026, Cayden Wyatt Costner is 19 years old. He recently finished high school. He has grown up into a calm and polite young man, often described as quiet and respectful during public appearances. But there is still a lot people don’t know about him.

Cayden Wyatt Costner weighed 7 pounds and 14 ounces when he was born. His father was 52 years old at the time. Kevin later shared that he had worries about being an older dad. He wondered if he would have enough time and energy to guide his son through life.

In interviews, Kevin admitted he wanted to be there to teach Cayden what it means to grow up into a strong and kind man. He even joked about pretending to sleep longer to avoid diaper duty. But behind the jokes, you could tell he deeply cared.

From a young age, Cayden Wyatt Costner was protected from too much public attention. His parents believed children should grow up feeling normal, not famous. Instead of flashing cameras every day, he had family dinners, school days, and time to just be a kid.

Isn’t that something every parent wants for their child?

Cayden Wyatt Costner’s Parents, Kevin Costner and Christine Baumgartner

Cayden’s parents were once seen as one of Hollywood’s strong couples. Kevin Costner married Christine Baumgartner in 2004. Christine is a former model and handbag designer. She even started her own handbag business called Cat Bag Couture.

Their marriage lasted 18 years. They built a family together and welcomed three children: Cayden, Hayes, and Grace. For many years, their life looked happy from the outside.

However, in May 2023, Christine filed for divorce, citing irreconcilable differences. The divorce received a lot of media attention. There were court discussions about child support and living arrangements. By early 2024, the divorce was officially settled.

Even though their marriage ended, both Kevin and Christine have continued to support their children. In fact, they both attended Cayden Wyatt Costner’s high school graduation in 2025. That shows strong co-parenting, even after a difficult split.

Cayden Wyatt Costner and His Graduation in 2025

His siblings Hayes, Grace, and even his older sister Lily were there. It was a reminder that family can still come together for important moments. For Cayden, graduating high school marked the beginning of a new chapter in life.
