Emily Blunt reveals secret passion for famous co-star

She has a handsome husband-to-be but that didn’t stop Emily Blunt following another man around like a "lovestruck teenager" on the set of her most recent film.

The 26-year-old actress co-stars with legendary actor Anthony Hopkins in new horror flick, The Wolfman, and found herself completely enamoured with the Welsh star.

"He invited me over for baked potatoes topped with baked beans and cheese to talk about our characters. So we were pals," gushed the beautiful brunette at the Hollywood premiere this week.

"He's very cool. He's the best. I was riveted by him… I just followed him round like a lovestruck teenager.

"I would sit around and talk to him between takes and he'd tell us wonderful stories.

"He is very wise, very open and incredibly kind. He hasn't lost that childlike enthusiasm for creating a part."
