Charlie Sheen & Brooke Mueller Expecting!

Two and a Half Men star Charlie Sheen and his wife of three months Brooke Mueller announced today that they're expecting a little bundle of joy in the coming months. It will be the first child for the couple, expanding Charlie's brood of three girls: Sam, 4, and Lola, 2 (with ex-wife Denise Richards) and Cassandra, 23 (with former girlfriend Paula Profitt).

“Brooke and I are thrilled!," Charlie tells OK! " She’s the best stepmom Sam, Lola and Cassandra could ever hope for. Seeing her love and affection with those three, I know she’ll be an amazing mom."

As for whether it's a girl or boy, Charlie is talking statistics: "Unless I bat 100%, perhaps a boy awaits us." he says.

OK! brought fans the exclusive pictures from Charlie and Brooke's wedding last May, a small affair in front of close friends and family.
