Sarah Silverman must have been using protection. Matt Damon and his wife Luciana are expecting their second child together, the box-office heavyweight's rep confirmed shortly after Luciana brandished a baby bump at Sunday night's Empire Awards in London.

The couple, wed in December 2006, are already parents to two daughters: Isabella, born June 2006, and Alexia, 9, from Luciana's previous marriage.
