I inherited this collection of vinyl records, which at that time numbered 6,000, and I've since continued to collect music. As you know, vinyl records can be very heavy, so every time I have to move into a new house, I need to build a complete new wall of shelves to put all these records, which is a nightmare for the architect.

I think the simplest way to break the ice is probably to try playing on the same level, to discuss everything in normal life. So, for example, with Katie Holmes, we just spent one hour talking about her daughter. Or with Madonna, when we were working on the event in New York, we spent hours deciding every single aspect together, from the dishes to the flowers to the cards.

When I joined Gucci in 2002, I immediately wanted to make a research trip into the archives because I'd heard about how incredible they were, but I never had the opportunity to visit them.

For me, beauty and fashion are always connected. One doesn't exist without the other. Make up is a key element of the Gucci runway show - it helps communicate the essence of the Gucci woman. Eyes, skin, lips - they're like accessories, all working together to create an unmistakable look.

I'm used to spending a lot of time with my team. They're not only collaborators, they're also friends. It's the biggest part of your life that you share with these people. But sometimes being on the top of this pyramid, you need to be a little bit tough. This job is becoming very tough for every company because of timing. You don't have the time to finish the collection before you have to think about the next one. But I am never loud. I don't like to scream. So we are all working hard, and sometimes you need to reassure them.

All the drawings and sketches and clothes of Yves Saint Laurent in the '70s were so colorful, so bright.

I always loved the look of musicians. I've always admired them because they have a look - when I was growing up, it seemed that the ones I liked didn't need to have a stylist. Now there is this trend where everyone has a stylist, or follows the suggestions of a stylist, from designers on down.
