Damon, 39, and Luciana, 34, are already parents to 3-year-old Isabella and 21-month-old Gia. Luciana's daughter Alexia, 11, is from a previous marriage. The couple were married in December 2005.

As for having kids Damon said recently: "They kind of disabuse you of the notion of your greatness pretty quickly. There's a routine that you get into with kids that precludes you from going back to your single days. I'm probably more boring than I used to be. I go to bed earlier and I get up earlier."
