Charlie Sheen has a baby on the way.

The actor is expecting a child with wife Brooke Mueller, Sheen announced Monday in a statement.

"Brooke and I are thrilled!" the star of the CBS hit "Two and a Half Men" wrote. "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. Unless I bat 100 percent, perhaps a boy awaits us."

Sheen has three daughters: 25-year-old Cassandra Jade Estevez, whose mother is Sheen's former girlfriend Paula Profit, and two girls with ex-wife Denise Richards. Sheen and Richards are still embroiled in a bitter custody battle over 3-year-old Sam and 2-year-old Lola.

Sheen and Mueller, a real estate investor, tied the knot in late May.
