When I was the first time for a job in New York, I saw Natalia Vodianova on an oversized billboard in Times Square on a Calvin Klein billboard.

It's not like I'm sitting at home coming up with some secret beauty plan. I try to eat fruit and be healthy. If I'm feeling a bit sickly, I usually get a good spray tan.

Most people can be made to look beautiful - someone can do your hair nice and put some make-up on - but being sexy is something inside and not everybody has it. I don't think I ever really had it, a lot of it is to do with confidence.

People were like, "Oh maybe we can change your teeth" and I thought that was going a bit far. You have to be really strong in this job and realise that you are your own boss and if someone tells you to do something, you don't have to do it. I really like my teeth.

People found me ugly and weird looking. All those years of that whole insecurity thing just makes you feel horrible then really slowly you start to think if they can make me look nice in the picture then it's not that bad.

I just like a good, honest personality. I like a real person, not somebody who is pretending to be something that they're not. That really annoys me.

I would probably advise myself 10 years ago not to take life too seriously and to just try to be happy.
