The Oscar-winning actor and his wife Luciana Bozan are expecting another child, reports People.

"They couldn't be happier," says rep Jennifer Allen. "They're so excited."

There were no details about the expected sex of the child or due date.

Bozan, an interior designer and former bartender, has a daughter, Alexa, from a previous relationship. The couple met while Damon was filming the Siamese twin comedy "Stuck on You" in Florida and dated a year and a half before becoming engaged. They married in December 2005 in New York in a private ceremony and had a daughter, Isabella, in June 2006.

The 37-year-old Damon's latest credits include "Ocean's 13," "The Good Shepherd" and "The Departed." He's currently shooting the CIA thriller "Green Zone" in Morocco.
