When people ask how have I kept on top, I have to say with the help of every photographer, make-up artist and hairdresser I've ever worked with.

I don't happen to think magazines should be full of thin people. What I do say is that we can all work a little harder with what we have. It is possible to achieve a better body shape and heart rate with nutrition and exercise.

When I started in the business, I was told I had three good years in me.

I know that sometimes the chemistry just isn't there between the model, photographer, hair and make-up. It's nobody's fault and you just have to do better next time.

I never, ever used my son for publicity. He'll have his say one day if he wants it. He'll have the last word. He has time to defend himself.

I'm part of a team that raises millions of dollars and raises awareness of HIV and AIDS all over the world.

I have to hit the gym. I have beauty appointments. I have to work toward my next job and maintaining my image, just like an athlete.
