It sounds like the plot of a romantic comedy: John Krasinski wasn’t looking for love – but then he met Emily Blunt.
The Office actor, 31, says he knew right away when he met the actress, whom he married last July, that she was special.
“It was one of those things where I wasn’t really looking for a relationship and I was thinking I’m going to take my time in L.A.” Krasinski says on Wednesday’s episode of The Ellen DeGeneres Show. “Then I met her and I was so nervous. I was like, ‘Oh god, I think I’m going to fall in love with her.’ As I shook her hand I went, ‘I like you.’ “
