Congratulations to Jason Sudeikis and Olivia Wilde! The former 'Saturday Night Live' star and 'House' actress are expecting their first child.

A source close to the couple confirmed the pregnancy to PEOPLE, as did their reps. The insider revealed, "They are incredibly happy. They're very excited to welcome a new member into their family."

Sudeikis and Wilde first met on the set of the 2011 season finale of 'SNL,' but didn't begin dating until six months later. They announced their engagement in January, though no wedding date has been set just yet.

"He's so good with kids," Wilde previously gushed to Marie Claire. "I'm open-minded about how many, but three is like a little party." Yeah, until you're dealing with three sets of dirty diapers, Olivia!
