Liam Costner Quick Bio

Who Is Liam Costner?

Liam Costner is the son of Kevin Costner, one of Hollywood’s biggest stars. But Liam is not in movies or on TV. Instead, he lives a private life and works hard in a completely different field — real estate.

Liam was born on November 15, 1996, in Los Angeles, California. In 2025, he will be 28 years old. He is known for being the son of Kevin Costner and Bridget Rooney. Even though his parents are famous, Liam chose to stay away from fame and create a quiet life for himself.

People are curious about Liam because he has a famous last name, but doesn’t act like a celebrity. Isn’t that interesting? Let’s learn more about his family.

Liam Costner’s Famous Family

Liam comes from two very well-known families. His father, Kevin Costner, is a famous actor, director, and producer. Kevin has won big awards like Oscars and Golden Globes. He is known all over the world for his great work in Hollywood.

On his mother’s side, Liam is part of the Rooney family. The Rooneys are famous for owning the Pittsburgh Steelers, one of the most popular football teams in the U.S. His mom, Bridget Rooney, comes from this powerful sports family.

But that’s not all. After Liam was born, his mom married Bill Koch, a billionaire businessman. So Liam grew up with connections to both Hollywood and a very rich business family.

Liam’s Early Life

Liam’s life began during a short romance between Kevin Costner and Bridget Rooney. Their relationship happened in the mid-1990s, right after Kevin’s divorce from his first wife. They kept their romance private, but when Bridget became pregnant, it made news.

At first, Kevin was not sure if he was the father. So, there was a paternity test. The test later confirmed that Liam was indeed Kevin’s son. After that, Kevin stepped in and set up a trust fund for Liam to help with his future.

Even though Kevin and Bridget didn’t end up together, they both cared for Liam. Liam mostly grew up with his mom and stepdad, Bill Koch. His childhood was full of love and support, even if his parents weren’t together.

Where Liam Grew Up

Liam grew up in a huge and beautiful home with his mom and Bill Koch. Bill Koch is very rich. Their home was more like a mansion, with many rooms, big gardens, and even art pieces worth millions of dollars. Imagine living in a house so big you needed an intercom to talk to family members in other rooms!

Liam had everything he needed — a safe home, a good school, and a loving family. Even though his biological dad, Kevin, wasn’t always around, Liam had a strong father figure in Bill Koch. Bill supported Liam like his own son and helped provide a stable and happy life for him.

Liam Costner’s Siblings

Liam is part of a big family. From his dad Kevin’s first marriage, Liam has three older half-siblings: Annie, Lily, and Joe. Annie is a film producer, Lily is an actress and singer, and Joe works in sound production for movies.

Then, from Kevin’s second marriage, Liam has three younger half-siblings: Cayden, Hayes, and Grace. These younger siblings have grown up in the spotlight a little more because of Kevin’s fame, but they all share a special family bond.

Liam also has a half-sister, Kaitlin, from his mom’s marriage to Bill Koch. So, Liam has siblings from both sides of his family, and he is part of a big, blended family that cares for each other.

Liam’s Relationship with His Father

At first, Kevin wasn’t very involved in Liam’s life. But once the paternity test proved that Liam was his son, Kevin accepted him and made sure Liam was taken care of. Setting up a trust fund was one way Kevin showed he cared.

Kevin didn’t live with Liam, but he visited when he could. Over time, they built a respectful and caring bond. Kevin often talks about how much he loves all his children and how important it is to treat them all with love.
