As a teenager, you're still discovering who you are, what your life is about, and who you want to be as a person. It's very intense.

I've missed London so much for its fashion. No disrespect to the girls in Manchester, but some really do look like clones - there's a lot of hair extensions and fake tans. You're free to experiment down here.

I've just made a cancer drama, called 'Now Is Good,' directed by Ol Parker and starring Dakota Fanning. We filmed in Brighton and it's about a girl dying of leukemia, although it's not as depressing as it sounds.

I wanted to do an action-y thing, purely because I'm the least fit, healthy person in the world. I wanted to prove to myself that I could actually run and not get out of breath and collapse. I wanted to push myself, in that way.

It was really cool to work with Dakota Fanning. I've watched her grow up and I've always loved her films, loved her. It was amazing working with someone who was American as well, because obviously it's going to be a different energy straightaway. We got on really well; she's so professional and hardworking.

Clothes are my drug. I love Camden market - I have so many vintage pieces from there it's unbelievable. Clothes are really important to me, they give me that feeling of happiness. I love being a bit free with it all and not giving myself rules.

My mum has told me that I have to work with Antonio Banderas just so that she can meet him and try and marry him.
