An Affair to Remember
After divorcing from Silva, Costner went on to have a brief affair with Bridget Rooney, who was described by Parade as a Pittsburgh Steelers heiress. She fell pregnant and claimed the baby was Costner’s – however, allegedly, he demanded a paternity test before he accepted the baby boy, born in 1996 and named Liam, as his own. Rooney consented, and the results revealed Liam was, in fact, Costner’s son.

Despite the rocky start to their father-son relationship, Costner later set up a trust fund in Liam’s name after the results of the paternity test were revealed. According to a source who spoke to People magazine, Costner saw Liam “occasionally but not on a regular basis.” By now, at age 41, Costner had four children.
