I was 14 when I started modeling. At the end of that first day my mum said, 'If you want to do this, you're on your own because I'm not traipsing around London ever again like that. It's a nightmare.'

When people see an actor speak, they think they know him or her, whereas I'm just a face or a body to them.

It was kind of boring for me to have to eat. I would know that I had to, and I would.

Once I was walking from The Mercer in New York - because otherwise I don't walk anywhere - and this woman paparazzo who was following me fell over a fire hydrant and her whole tooth went through her lip. I leant over her, saying, 'Are you all right?' and she was still taking pictures.

I'd go on the train to castings, changing from my school uniform on the train. I carried on like that for a few years, getting jobs in bits and pieces.

I hate dentists. That's why my tooth fell out. I was in the middle of a root canal and wouldn't go back, so it just dropped out when I was in the middle of Fifth Avenue. I had to do the Calvin Klein show without the tooth.

My daughter Lila loves the smell of gasoline - she always says, 'Mummy, keep the door open,' when I'm filling up the car. I've heard it is one of the most preferred scents in the world - maybe that's something to study for my next fragrance!
