Who Is Liam Costner?
Liam Costner was born on November 15, 1996. That means, he will be 28-years-old in 2025. He is the son of Kevin Costner who is an accomplished actor with a number of popular movies such as Dances with Wolves, Yellowstone, The Bodyguard and many others. Liam’s mother is Bridget Rooney, who is part of the famous Rooney family that also owns the Pittsburgh Steelers.
Liam Costner hasn’t lived like most celebrity kids who grow up in the limelight. Many people really don’t know anything about him until they see a news story or a family picture. This is because Liam has quieted his life significantly.
He has never acted, he hasn’t given interviews, and he doesn’t seem to chase fame the same way many other kids do. From all accounts, he has created a quiet life.
The History of his Parents
Liam was born from a short relationship between Kevin Costner and Bridget Rooney in the mid-1990s. At the time, Kevin had just come out of a long marriage and was one of the biggest Hollywood stars. Bridget came from a long line of business people and powerful sports and team owners.
After Liam’s birth, there was some talk in public about whether or not Kevin Costner was the father. Reportedly, Kevin requested a paternity test, and the paternity test did confirm that Liam was his biological son.
Growing Up Away From Famous
Liam Costner, although well known around the world because of his dad, grew up a lot differently than most. He didn’t live with Kevin full time; he never fully joined the Hollywood entourage, and he was raised primarily privately by his mom.
In many ways, Liam’s childhood was different from many children of celebrities, with no red carpet photos, no acting cameos, and no interviews; he really was an everyday kid with a famous last name. That is ironic I guess, but it also contributes to why his story is so interesting. In a time when so many children of celebrities pursue fame, Liam has chosen the opposite.
The Costner Family: Big, Famous, and Messy
Liam is among seven children that Kevin Costner has with three different women. His older half-sisters and brothers—Annie, Lily, and Joe—were born during Kevin’s first marriage to, Cindy Silva. They have worked in entertainment and continue to do media interviews.
There is then Liam, with he and Bridget Rooney. Kevin then married Christine Baumgartner and with her had Cayden, Hayes, and Grace. And as of 2025, a grown-up, or nearly grown-up kid, for all of the seven kids, and many keep pretty private just like Liam.
Where is Liam now? What does he do?
So what does Liam Costner do if not Hollywood? As of 2025, reports TechRifle, Liam is working in real estate. He is a licensed agent in North Palm Beach County, Florida and is associated with the Frankel Bell Group. It’s a big transition from California, but so far he seems to fit in.
Liam’s job consists of helping people purchase and sell homes. He especially specializes in upscale areas of the Sunshine State. It’s a lucrative business and, beyond that it means he has a professional life on his own terms. It doesn’t come with public Instagram account or a flashy lifestyle. He does his job and gets on with his life.
How rich is Liam Costner?
People assume he must have a large net worth because of his prominent family. And, they are probably right. While Liam doesn’t flaunt money there are several knowns.
First, Kevin Costner confirmed he was Liam’s father prior to his whatever estrangement took the relationships off his social agenda, Kevin evidently created a trust fund for Liam. No dollar amount has been disclosed, but some speculate the trust could be worth millions. Further, Liam is in real estate.
In North Palm Beach, a real estate agent can makes a lot of money. This is particularly true where a lot of the house value is infused into oceanfront estates or prime residential locations.
Why Are People So Interested in Liam?
So, you might wonder—why do people have such strong opinions about Liam Costner when he seems to live a decidedly private life? That is a great question. A large part of the curiosity is that his last name is Costner. The name Costner is synonymous with Hollywood. You have to feel that any fan of Kevin’s instantly wants to know more about him, his family, and their life outside of his movies. When they find out he has a son named Liam, who doesn’t appear in a lot of news or social media, they will be even more curious.
There’s also the intrigue. Liam has never done one interview, has never been on any talk shows, and has never posted about himself outside of his acting/improvising roles. People want to know more about Liam. You can find people searching for photos of Liam, trying to stalk him on Instagram – only to find that he doesn’t have an Instagram.
Liam’s Current Life: Quiet, Simple, and Private
So what does Liam Costner do in 2025? He still lives a quiet and private life. He works full time as a real estate agent and helps people buy and sell their homes. He’s not on television. He’s not in the news. And he does not post anything on social media.

But you can tell that Liam has always appreciated his privacy and prefers to build on his own life rather than being followed by cameras. He is not an attention seeker. He’s not fighting for celebrity status. He’s just living his life – quietly, on his own terms.
Final thoughts
Liam Costner could have, without question, followed in his dad’s footsteps to Hollywood. He could have leveraged his last name to gain attention or to become famous. But he did not. Instead, he took a different path of least resistance – one that most people would not have chosen in the same situation.
He built a career in real estate, removed himself from the public eye, and enjoyed a calm, simple life. He may not be making headlines, but that does not mean his story isn’t worth telling. It proves, if nothing else, that not every child of a celebrity is trying to be famous, some, like Liam, want to live like everyone else.
