Some girls like to say one thing and mean another. And me being who I am, I'm very straightforward. Everything is very black and white for me. I don't really like playing mind games.

I'm always drawing, so Draw Something is a cool game to play against your friends when you're bored and sat chilling out and relaxing.

The amount of hot girls who come to signings is incredible!

I do feel like I've missed out a bit because I was really close with my sisters when I was at home. It must be weird for them but they cope really well.

We needed to make a sound that's not gonna fit in with everything else - we wanted to make something that was completely unique and individual to us. We spent a lot of time trying to make a sound that was a One Direction sound. At first it was quite hard to do that, but I'm really happy with the sound.

When we were on 'The X Factor,' we didn't realize how overnight the fame thing was. We didn't really understand it until we went on a shopping trip. It was like Week 7 or 8 of the show. We went with a few other contestants and there were loads of people, packed.

We didn't really expect to achieve anything outside of the UK, and it just went crazy. It's just crazy that people know our music. We're just humbled by it.
