I can't drive, so I don't need a flash car, and I like living at home, so I don't need a mansion. I'm sensible with money. It's not why I act.

I can be immature. I know I can when I'm at my dance lessons or something. I become like the class clown. I don't know why. But I can flip in and out of it - if I need to be mature I can be mature, but if I want to have a bit of fun, I'll have a bit of fun.

I went to a fancy dress party as a punk. I went through a stage of being a wannabe punk from the '70s. So, my next-door neighbours were like hardcore punks and I went to see The Vibrators and came home with a T-shirt that said "The Vibrators". My mum said: "You're not going out in that!" But I was really into it. I did soon grow out of it. But that's probably the most embarrassing story I have. I really am just quite normal.

I think you grow up on every shoot you do. You do grow up because you're away from home, you're not with all of your friends constantly and in that environment you have to be grown up. You're working with adults and you're sort of expected to be older and that's how I like to put myself across. I don't want to come across as constantly messing about.

There are times when I will dress up, like tonight for the premiere, but there are times when it doesn't matter. It's not that I think it's fake, but I'm not going to go out of my way to be something that I'm not.
