I think there's so much feeling among young girls where they feel like they have to be this perfect thing - and they don't. Perfect people don't exist. Sometimes people need to be told it.

I want to sell out arenas and make an album and work with some of the best artists in the world.

I don't know, it's odd that girls ask if they can hug me. Don't ask, do it. I'm just a regular guy

A personal highlight was probably when we got a No. 1 in the U.K. and when the album went to No. 1 in America. The top four that week was us, Adele, Guns N' Roses and Bruce Springsteen. It was ridiculous seeing those names there. Being the first band from the U.K. and Ireland to go to America and debut at No. 1 is just unbelievable.

Katy Perry is the sexiest woman I've ever kissed. It was amazing and very purple - she had purple lipstick on. I don't think there will ever be anything cooler than kissing her until I marry her maybe!

I've got my old favorites like The Eagles and Bon Jovi.

I'm quite claustrophobic, and I don't like everyone crowding around and shouting the same questions.
