Who Is Liam Costner?
Liam Timothy Costner is best known as Kevin Costner’s son, but that’s not the full story. He is a real person with his own path, dreams, and choices. Liam was born on November 15, 1996, in Los Angeles, California.
Even though his dad is super famous, Liam stays away from the spotlight. He doesn’t appear in movies, interviews, or Hollywood events. He lives a very private life. Most people only know him because of his famous last name.
Today, Liam works in real estate. That means he helps people buy, sell, or rent homes. It’s a simple job, but one that he enjoys. He has chosen success in his own way, far from cameras and fame.
Liam Costner’s Birth and Early Life
Liam was born during a short relationship between Kevin Costner and Bridget Rooney. At that time, Kevin had just ended a 16-year marriage and wasn’t ready for another commitment. So, Liam’s birth was a big surprise.
At first, Kevin wasn’t sure he was the father. He asked for a paternity test, and when it confirmed he was the dad, he took full responsibility. He didn’t marry Bridget, but he set up a trust fund to secure Liam’s future.
Liam mostly grew up with his mom, away from the noise of Hollywood. While many celebrity kids go to movie sets, Liam was playing sports and living a peaceful life. He didn’t grow up in the public eye, and that helped him stay grounded.
Liam Costner and Kevin Costner’s Relationship
So, what kind of bond do Liam and Kevin have? It’s quiet, but strong. After the paternity test, Kevin began to support Liam financially. He didn’t raise Liam full-time, but he stayed in touch and made sure his son was cared for.
As Liam got older, their relationship grew. Kevin never ignored his duty as a father. Even though they didn’t live together, Kevin included Liam in family matters and kept the door open for connection.
In past interviews, Kevin has talked about how much he loves all his kids. He once said his children are the “anchor” of his life. That includes Liam. Kevin knows that love doesn’t have limits, and every child deserves that love—no matter the situation.
Liam Costner’s Mother, Bridget Rooney
Liam’s mom, Bridget Rooney, also comes from a very famous family. She is part of the Rooney family, who own the Pittsburgh Steelers football team. So while Kevin brought Hollywood, Bridget brought sports and legacy.
Bridget was 34 when she got pregnant with Liam. In one interview, she said, “I’m 110% sure who the father is. I’m just enjoying my pregnancy.” She stood strong, even when the media made things hard.
Later, Bridget married Bill Koch, a billionaire businessman. He accepted Liam and raised him like his own. Bridget gave Liam a calm, stable life. She didn’t push him into acting or media. Instead, she let him grow at his own pace.
Liam Costner’s Stepfather and Wealthy Upbringing
Liam’s stepfather, Bill Koch, is a well-known businessman. He’s part of the Koch family, one of the richest families in America. Bill married Bridget Rooney in 2005, and they had one daughter together.
Growing up in a home with Bill Koch gave Liam many opportunities. He lived in a beautiful house, got a good education, and saw the business world up close. While other kids were dreaming of movie sets, Liam was learning about investments and real estate.
Bill also taught Liam the value of hard work. Even though Liam had access to money, he didn’t rely on it. He decided to build his own career. That’s a big reason why Liam Costner chose real estate over acting.
