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 can take critism, but if it's like 'I don't like you' then I want to know why people don't like me. Why do you hate me? What have I done?

I don't want to be viewed as a womaniser or whatever. I don't like going crazy crazy, I like having fun but it's nice to wake up in your own bed, isn't it?

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.

I can see how you could get dragged into the bad stuff, but I've got good friends around me, good family. I think I've got my head screwed on.

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!

A dream is only a dream.. until you decide to make it real
