In April 2007 I learned that Yves Saint Laurent had a brain tumor, and he died on June 1, 2008. During those 14 months I had plenty of time to think about what would happen. There was only one solution: the auction. An auction establishes memory. That's what I want to do.

I love Marcel Proust, but I leave him to his nostalgia. I don't approach art the way most people do. I don't get into Proust by imagining that I am Charlus or whoever. It's the same thing in painting - I try to look at it objectively. There's no pathos in that. It's like Bach's "Goldberg Variations." They have to be approached with a scalpel.

Let's talk about that for a moment, about the couple that Yves Saint Laurent and I were. Like all couples we went through "storms," as the Jacques Brel song says. But if there's one area where we never had the slightest disagreement, it was art. Never. Not once. Not about painting, not about opera, not about theater. We were always in complete communion. Of course, that's how all of the collection came into being.

I am a man who has spent more than half a century ostensibly and visibly accompanying Yves Saint Laurent throughout his life - but not only that. In the past and still today, I have been behind a lot of creators and artists, supporting them and helping them. That's probably how I see my mission.

Love is what makes me live, quite simply. It's the only thing that makes me work. It made me become what I am today.

I met Andy Warhol in the '60s, a wonderful time, with wonderful people. There was Fred Hughes, and Jed Johnson, who I liked a lot. Jed Johnson decorated my apartment in New York, at the Pierre. It was his first job.

I've already bought another house in Tangier and the one in Deauville has been for sale for some time. As for Yves's Saint Laurent apartment, it is being sold because he's dead. But I won't be furnishing my home from Ikea.
