I haven't had surgery. I've had my teeth done, which was a massive insecurity for me. But I'm one hundred percent happy. It's difficult, not just for people in the media, but for everyone - young girls and boys - especially in high school.

I just want my songs to be memorable, and for people to hear my songs in ten year's time and remember the great times they had while listening to 'em.

I've been incredibly lucky throughout the beginning stages of my career up 'til now, and so lucky to work with the incredible people I've worked with.

In school, I was the quietest girl ever! I had a lot of trouble in school. Kids were mean to me.

This whole 'X Factor' thing with people assuming I'm going to be a one-hit wonder - that won't happen with me.

There are lots and lots of different films that I love, and watching different characters and how different people play them.

I think it's really important to do what you want to do because in the long-run it's your career, you want everything to go well and you want to be happy with what you're doing. It was really important for me to take control of my career.
