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 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.
