Emily Blunt and John Krasinski are going to be parents!

The 30-year-old actress and the former "Office" star, 33, are expecting their first child together, a rep for Blunt confirmed to ABC News.

"It's hard to sum up something that's so vital and means everything to you in a sound bite. Do you know what I mean?" the "Devil Wears Prada" star told Modern Luxury Manhattan magazine in 2012. "All I can say is that it's an effing blast. It's just great, and I'm so happy."

The couple, who were married in 2010, had always planned to have children, she said.

"We want to have children; I just don't know when yet," she said at the time. "I'm just not sure about the timing of all of that. We're both from big families so I think it's something we want."
