Following the announcement of their engagement, back in January, the couple have just confirmed they will become parents.
“They are incredibly happy,” a source tells PEOPLE. “They’re very excited to welcome a new member into their family.”
In a previous interview with Marie Claire, the actress opened up about the possibility of growing a family with the actor. “He’s so good with kids. I’m open-minded about how many, but three is like a little party.”
Upon receiving congratulatory messages from fans the actress also tweeted, “WOW. You guys are awesome. So kind. Thank you thank you thank you! PS. Babies eat mostly salsa right?”
The duo met after meeting on the set of ‘Saturday Night Live’ back in 2011. They began dating six months later and, as they say, the rest is history.
Congratulations Jason and Olivia!
