John Krasinski & Emily Blunt Check Out 'It's Complicated'

John Krasinski and Emily Blunt are smiling sweethearts at the New York premiere of It’s Complicated at New York City’s Paris Theatre on Wednesday (December 9).

USA Today caught up with John, 30, on the red carpet, and he explained that a sense of humor is important to a successful relationship.

“Being able to laugh with another person is such an amazing gift that I think it can make things extremely fun, but it’s the only way to get through the bad times,” he said. “The mind is a scary place. When you laugh it releases the tension and you can get through anything.”

Don’t miss John on tonight’s episode of The Office – 9/8c on NBC!
