The Office star John Krasinski felt sure his girlfriend Emily Blunt would dump him after he saw her in 2009 movie The Young Victoria - because it suddenly hit him that she was way out of his league.

The actor had only been dating the Brit for three weeks when he accompanied her to a screening of the period movie - and he admits he was completely dazzled by her performance.

He tells C magazine, "You're like, 'Boy, I wonder who she's going to date starting tomorrow... because it sure as s**t ain't going to be me.'"

But Blunt had found her ideal man and the couple wed a year later.
