Actor Kevin Costner has seven children, but the least known is his illegitimate son, Liam. We tell you everything we know about him.
Kevin Costner has been married twice. His first marriage, to Cynthia Silva, lasted from 1978 to 1994 and produced three children: daughters Annie and Lily and son Joe. His second marriage, to Christine Baumgartner, lasted from 2004 to 2023 and also produced three children: two sons, Kayden Wyatt and Hayes Logan, and a daughter named Grace.
But toward the end of his first marriage, Costner had an affair with a woman named Bridget Rooney, the niece of then-Pittsburgh Steelers owner Dan Rooney. The boy was born in 1996, but Kevin’s relationship with his mother began earlier. The exact date of their meeting is unknown, but they met while playing golf. At the time, Costner was still married to his first wife, Cindy. Kevin and Bridget’s relationship reportedly lasted three years.
When Liam was born, the Hollywood actor initially refused to acknowledge him, but a paternity test taken by Bridget left no doubt.
A year after Costner married for the second time, Bridget also married. And not just anyone—her choice was American billionaire and business magnate William Koch, who became the boy’s stepfather. William and Bridget also have a daughter together, Caitlin, and the billionaire has four more children from previous marriages.
Liam keeps a low profile in the public eye. The young man works as a luxury real estate agent and now goes by the name Liam Rooney Koch. Little is known about his personal life, but estimates of his net worth have been made online. These estimates place it at at least $800 million, with $40 million of that coming from his biological father, Kevin Costner.
