The Diehard actor's wife, Emma Heming, 33 is pregnant with her first baby, and Bruce's fourth. He already has three children, Rumer, 23, Scout, 20 and Tallulah Belle, 17 from his marriage to Demi Moore.
A statement announcing the couple's happy news said Bruce and Emma are "overjoyed with this news and they look forward to welcoming this newest addition into their family".
The couple's new arrival is due early next year.
