Emily Blunt is expecting her first child with husband John Krasinski.

According to Us Weekly, the 30-year-old actress and 33-year-old The Office actor "are set to welcome a tiny bundle of joy in just a few months' time."

"They both want kids, it's one of the reasons they got a bigger place, in a neighborhood that you can raise a family," a source said, "They both couldn't be more excited."

The Devil Wears Prada star and Krasinski started dating in November 2008 and were married in 2010 in a ceremony that took place in Italy.

"I feel like everyone poo-poos actor relationships because they say they always end in divorce and tears," Blunt told The Times in April 2012, "But that's only because it's in the news and it's broadcast to the world. John and I can talk about everything, and it's nice, because we have a very deep understanding of what the other person does."

Blunt has also spoken about the couple's desire to start a family.

"We want to have children; I just don't know when yet. 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," she told Manhattan magazine in May 2012.

A friend close to Krasinski revealed that he wanted to take up paternal duties since a long time.

"John has been talking about wanting to be a dad for a long time. He said that as soon as he was finished with The Office, he and Emily were going to start really trying. Guess he has fast swimmers cause it didn't take them too long!" a source told Hollywood Life.
