Ethan Suplee and his wife Brandy Lewis will add to their growing brood in April

My Name is Earl actor Ethan Suplee tells PEOPLE that he and wife Brandy Lewis will welcome their fourth daughter in April.

At Sunday’s 14th Annual Diversity Awards in Los Angeles, where the show was honored as the year’s favorite comedy ensemble, Suplee revealed a budding seed of envy towards costar Jaime Pressly, who recently announced that she is four months pregnant: “My wife and Jaime are pretty close (in due dates). But Jamie is having a boy and I am so jealous of that and I want nothing to do with it!”

Suplee, 30 and Lewis, 30, welcomed their daughter, Francis Clementine Suplee, last year. Plus, Lewis, whose sister is actress Juliette Lewis, has two daughters Bella and Lily from a previous marriage.

With the upcoming addition of daughter number four, “that makes four girls, which really means five girls versus me in the house,” says Suplee. “It was just me trying and trying for a boy to balance out the voting system. I don’t think it’s going to happen.”

Over his summer hiatus, Suplee and Lewis tied the knot after a long engagement lasting over a year. According to Suplee, the simple, intimate wedding consisted of “me, my wife, the baby, and our nanny.”

He added: “There was a justice of the peace who came over and married us. The baby had some flowers but she was mostly just tearing them apart.”

Suplee, who is a Kevin Smith favorite and appeared in Mallrats, Chasing Amy, and Dogma, currently plays Randy Hickey, the dim-witted brother to Jason Lee’s title character Earl J. Hickey, on the Golden Globe-nominated show.
