I'm looking forward to being old, to be able to accept what I am and become self-sufficient. Mid-forties is a good age and it's not too far away.

I've lived on my own since I was 13 and not been to school and brought a son up who's now 18 and run theatre companies and bought a butcher's shop, learnt guitar by myself, taught myself to sing and that sort of stuff.

I had been painting Kate Moss for a long time, both before the time of her crisis and during it. I felt very strongly for her - she's a hard-working mum and it seemed as if suddenly the world turned against her. Holy water cannot help you now is painted in very warm pretty colours.

I wanted my work to be seen for free in a public space, I want to be up there with Pollock and de Kooning, one of the big boys.

I do have a very, very big problem with someone who saw me coming and exploited me as a mascot.

Perhaps the people I choose to paint are often objects of derision - celebrity is a bit of a put-down term, isn't it? But to me they are my world.

Even in the most horrendous situations there is always something to smile about.
