More fun than a barrel of monkeys? Will Ferrell to become a dad for third time.

People Magazine reports that the former Saturday Night Live star and his wife, Viveca Paulin, are expecting a third child.

The star, 42 and Ms. Paulin, 40, already have two sons, Magnus, 5 ½, and Mattias, 2 ½. The third child is expected to be a boy.

You’ve got to hand it to the mom. Jumping around with Will Ferrell alone has to be exhausting. I can’t imagine a house full of four of him.

The new baby is in January 2010, according to Ferrell’s representative.

Ferrell starred in last summer’s Land of the Lost. He also had a Broadway show early in 2009, featuring his George W. Bush impersonation that was nominated for a Tony Award.
