Until my early teens, I lived with my mother in New York, and I spent a lot of time in the company of her friends, mostly artists and designers, such as Andy Warhol, Ross Bleckner and Francesco Clemente, none of whom had kids, so I was like their shared child.

I sometimes clean my ears up to five times a day. Even having buds in the same room makes me want to have a go. When I'm in India, the cheap ones freak me out because I worry they'll drop off inside my ear. In the U.K., I like Johnson's.

Becoming a grandmother has felt like being a mother.

I listen to all sorts of music, but I'm not musically talented. Everyone expects me to be a good singer or musician, but I really am terrible. I'm a great dancer, though.
