John Krasinski, Emily Blunt Expecting First Child

Blunt, 30, and Krasinski, 33, were married in 2010.

"Meeting John really changed my life," Blunt, who will play the Baker's Wife in the movie adaptation of Stephen Sondheim's Into the Woods, told InStyle in April.

"When I feel the support I have from him, I feel invincible. There's someone behind you on your good days, and someone in front of you on your bad days."
