I wasn't the prettiest girl in class. No breasts, short legs, gangly teeth. I didn't think I was model material, that's for sure.

Americans are really obsessed with their teeth being white and straight, aren't they? I saw this little girl the other day with one of those whole head braces. Elastic all the way around! How traumatizing for a child to have to wear one of those! You look like a monster.

All of a sudden I was living what is perceived to be the model life. It was just full-on, 24 hours a day. It was work all the time. And there's always a party to go to.

I would have wanted to be a rock star, a lead singer, if I wasn't a model. I'd go touring in a bus with my band. In my next life, that's the plan.

Modeling can be a bit brain damaging. Starting my own brand was what I needed to do. I only model if there are such good jobs that you don't want to say no to. All that dressing up makes me say, 'What do I want to wear?' and, 'What do I want to do with Topshop?' It all kind of leads into the other things.

I'm happier on the runway than I am on the red carpet. Because then I am not being myself. I think, on the red carpet, it's a weird, like, 'Who am I? Am I me? Am I them?'
