Emily Blunt was "really star-struck" when she met her favourite rocker.

The actress may be one of the biggest stars in Hollywood, but still feels overwhelmed in front of other famous people. Emily was lost for words when she came into contact with Arcade Fire frontman Win Butler.

"I got really star-struck by the lead singer of Arcade Fire," she told British magazine Look. "I said, Amazing,' about 20 times in the space of two minutes and he was like, Calm down, it's OK.'"

Emily is married to actor John Krasinski. She says settling down with her perfect man has changed her life.

"It's more fun," she replied, when quizzed on married life. "I think we have the ultimate bond now and it's fun as hell. It just gets better and better for me and I think that's probably finding the right person. I love it."

Emily was also happy to dish out some advice for brides-to-be. The 29-year-old star believes couples should concentrate on what they want for their big day, rather than listening to loved ones.

"Don't have too many cooks in the kitchen," she warned. "It's your day, so it has to be what you want."
