Each time I spend with Stella McCartney, I like her better. So I was excited to be asked by her.

One of my assistants, a British man, says I should find a platform for [cosmetic industry]. Meanwhile I wear make-up.

I also photographed Maggie Cheung - but these didn't develop into a friendship either.

There are days when everyone in the world looks like a Diane Arbus to me. She's a genius but her work is completely different to mine. But on those days I don't use my camera.

My desire is to preserve the sense of people’s lives, to endow them with the strength and beauty I see in them. I want the people in my pictures to stare back.

In America, more than half the population are overweight. It's not healthy and I'm not proud of that but I don't hate having a woman's body.

I'm very flattered when people I respect like my work. It's like a dream of a little kid when somebody I idolised likes my work.
