Speaking to the Croatian women's magazine Story, Goran Visnjic confirmed that yes, he did have an affair with Mirela Rupic, the 36-year-old woman who earlier this week filed a paternity suit claiming that the ER star is the father of her 4-month-old daughter. "It is not something that I am proud of, of course," says Visnjic, who has been wed to Ivana Vrdoljak since 1999. "But I am ready to accept all the consequences of my act" and agree to a paternity test.
