Chloe Grace Moretz uncomfortable with Kick-Ass fans' unusual requests

Chloe Grace Moretz was once left stunned after a fan of her action movie Kick-Ass asked the teen star to hit him in the face.

The Hugo star, who plays ruthless vigilante Hit-Girl in the film franchise, reveals she is often left feeling a little uncomfortable by devotees' requests and one encounter last year (12) was no different.

She tells TV host Conan O'Brien, "I was at a Paul McCartney concert about a year ago and this guy was really drunk and he came up to me and he was like, 'Hey man, are you Hit-Girl?' There's a moment where you think, 'Maybe I lie' and say, 'I'm from, like, Arkansas and I'm visiting.' Then he's like, 'Will you just punch me in the face?' No I'm not going to punch you in the face, but thank you for asking."
