Charlie Sheen, star of hit U.S. television sitcom "Two and a Half Men," revealed on Monday that he and his wife Brooke Mueller are expecting their first child together.

Sheen, 42, married real estate agent and former actress Mueller, 31, this past May after a bitter divorce with actress Denise Richards in 2006. Sheen and Richards had two daughters from their previous marriage, and Sheen also fathered a girl with former girlfriend Paula Profit.

"Brooke and I are thrilled! She's the best stepmom Sam, Lola and Cassandra could ever hope for," Sheen said in a statement. "Seeing her love and affection with those three, I know she'll be an amazing mom. Unless I bat 100 percent, perhaps a boy awaits us."
