When I see Kate Moss out and about, I think she looks more beautiful than when her hairdresser and make-up artist try and make her look like something else. And I remember when Madonna first asked Versace to book me to shoot a campaign with her, she came to see me wearing hardly any make-up, and she looked incredible.

When I had photographed Prince William's mother, I brought along a CD of Dalida, a French singer, that we played on set all day to relax everyone. I decided to do the same thing for Catherine and William. The contrast of the contemporary informal music playing in the beautiful rooms with so much history caused a lot of laughter.

I'm fascinated by the ways in which people express themselves, because their responses are often counter to what they're actually feeling. Like when they're frightened, they tend to freeze. When they're angry, it doesn't always come out as volume. There are wonderful contradictions in the way that people express their emotions.

I don't think even when you find a person, you can be completely honest, ever. There's still pieces of you that you don't give away. I do believe you always need that place where it's just you, your thoughts, no one else's judgment or anything.
