Liam Costner was born on Nov 15, 1996 (28 years old), in the United States. While he’s the son of Hollywood star Kevin Costner and actress Bridget Rooney, Liam has largely chosen to live life outside the entertainment spotlight. Instead of pursuing acting or film like his father and some of his family members, he’s built a career in real estate, working with the Frankel Bell Group in Northern Palm Beach County, Florida.

Even with his famous last name, Liam has managed to create his own professional identity. His work focuses on helping clients find luxury properties in one of the most competitive real estate markets in the country.

Early Life and Family Background

Liam’s life began under unique circumstances. His parents, Kevin Costner and Bridget Rooney, were never married. Their relationship lasted only a short time, and they separated before Liam’s birth. At the time, there was uncertainty about paternity, which was resolved through a DNA test that Kevin himself requested. Once confirmed, Kevin acknowledged Liam as his son and provided financial support. Over time, their relationship developed positively, though Liam has kept much of that aspect of his life private.

Liam grew up with an extended family that includes six step-siblings. From Kevin Costner’s first marriage to Cindy Silva, Liam has three older half-siblings: Annie, Lily, and Joseph. All three have ties to the entertainment world, with Annie Clayton (his eldest half-sister) working as a Hollywood film director. From Kevin’s second marriage to Christine Baumgartner, Liam has three younger half-siblings: Cayden, Hayes, and Grace.

Although Liam has connections to acting royalty, he has always kept a low profile compared to many celebrity children. His upbringing was a blend of privilege and privacy, with his mother Bridget Rooney also being part of a prominent American family connected to the Pittsburgh Steelers football franchise.

Education and Privacy

Not much is publicly known about Liam’s education. Unlike many celebrity offspring who attend high-profile schools or share details about their academic background, Liam has kept this aspect of his life out of the public eye. What is clear is that he transitioned into real estate work as a young adult, a path that suggests strong interpersonal skills, market knowledge, and an interest in business rather than entertainment.

Career in Real Estate

Liam Costner works as a real estate agent with the Frankel Bell Group, a well-regarded real estate team in Florida. The group specializes in properties located in Northern Palm Beach County, including exclusive areas like Jupiter, Palm Beach Gardens, and the surrounding communities. This part of Florida is known for its luxury homes, waterfront estates, and golf course properties, attracting wealthy buyers from across the country.

In such a competitive market, Liam’s job involves much more than simply listing homes. His role requires networking, understanding local property trends, guiding clients through negotiations, and providing market analysis. Working in high-end real estate also means catering to a clientele that values discretion—something that aligns well with Liam’s own preference for privacy.
