Matt's First Born Ultimatum

Matt Damon and his wife are expecting their third child.

The 37-year-old's spokesperson told People magazine in the US: "They couldn't be happier. They're so excited!"

Matt and his wife Luciana let the cat out of the bag when they stepped out at the Empire Film Awards in London – with the 32-year-old glowing and sporting a baby bump.

The couple already have two children - their daughter Isabella was born in June 2006 while Luciana has a nine-year-old daughter, Alexia, from a previous marriage.
