I've been in the public eye for about 15 or 16 years and I'm very aware that fame is not a given. I have to maintain it. It's not just something that will always be there.

People always think I'm taller than I am - not just because of the shoes I wear but because of the way I dress. It's all relatively streamlined.

I was very obsessed. I mean, I could tell you the fat content and the calorie content in absolutely anything.

When I was on stage with the Spice Girls, I thought people were there to see the other four and not me.

These people are amazing. It's so emotional I was thinking about wearing waterproof mascara.

When I'm lying in bed I think about the next collection. That makes me sound insane, doesn't it? That I'm getting into bed with David Beckham and thinking about clothes.

I don't believe anyone who says they don't care what people say about them. Of course they bloody well do.
