Quick Bio of Liam Costner

Who Is Liam Costner?

Liam Timothy Costner was born on November 15, 1996, making him the fourth child of Kevin Costner. Unlike his father, who embraced Hollywood fame, Liam has maintained a remarkably private lifestyle. He rarely makes public appearances and has deliberately avoided the acting industry.

Instead, he has found success in the real estate business, particularly in Florida, where he works with high-value properties. His story stands out because he balances his famous lineage with his own determination to live away from the public eye.

Early Life and Family Background

Liam’s life began during Kevin Costner’s short relationship with Bridget Rooney, a woman with her own powerful heritage. Bridget is the granddaughter of Art Rooney, the founder of the Pittsburgh Steelers, making Liam connected not only to Hollywood but also to the world of American football.

After Liam’s birth, Kevin initially sought a paternity test to confirm his fatherhood. Once confirmed, he took responsibility by establishing a trust fund for Liam. While Kevin did not live with Liam during his childhood, his financial support demonstrated a sense of accountability.

Growing up, Liam primarily lived with his mother and later with his stepfather, Bill Koch, a billionaire businessman. This gave him a unique childhood—rooted in wealth, security, and opportunity.

• Bridget Rooney, on the other hand, hails from the Rooney family dynasty. Known for their ownership of the Pittsburgh Steelers, the Rooneys are among the most influential families in American sports.

Although Kevin and Bridget’s relationship was brief, their shared role in raising Liam ensured he had both financial support and a secure family environment. Bridget later married Bill Koch, and this introduced Liam to yet another world of affluence and business acumen.

Bond with Stepfather Bill Koch

Perhaps one of the most influential figures in Liam’s upbringing has been Bill Koch, his stepfather. Bill, a successful billionaire businessman, provided Liam with stability, security, and education opportunities.
