I'm quite old-fashioned. I like going out to dinner. You have the chance to talk to somebody and get to know them better.

Quite a lot of the girls I get photographed with are just friends and then, according to the papers, I have, like, 7,000 girlfriends.

You get moments all the time that kind of make you pinch yourself, some of them make you quite emotional. Winning a BRIT was a big moment because we were just so excited to be at the awards in the first place. Selling out Madison Square Garden was pretty amazing too. Then we woke to the news that our UK tour was sold out. It was crazy.

You're never going to get used to walking into a room and have people screaming at you. There's a lot of things that come with the life you could get lost in. But you have to let it be what it is. I've learnt not to take everything too seriously.

I wouldn't say I'm girl-crazy, because that makes me sound like a bit of a womanizer. That isn't really me. But I am quite flirty - maybe too flirty. I'm an 18-year-old boy, and I like to have fun!

I'm not really a pick-up-line guy. I don't know what I do.
