Smile doesn't mean that someone is happy. Sometimes it just means that you're strong.

If you meet a girl, you meet a girl. It's normal, so if you exchange numbers, whatevs, it's cool.

It's pretty strange because you have images of people in your head when you left, then you just think they're going to be the same when you come back, like time freezes. I have sisters and from the ages of 11 to 13 - it's a big change for girls.

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.

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.

I was a bit of a handful when I was a kid because I was quite hyperactive. Even in the house my mum used to put me in my pram because I was so full-on.

There comes a day when you realize turning the page is the best feeling in the world.
