On Christmas Day I'll head off for a couple of laps around the Serpentine, or a trek around the whole of Hyde Park. Or I'll walk right across town, with Curtis, my son Jamie's bull mastiff.

My working hours are not that conventional. I often get up about two in the morning and do a painting, and then I'll have a bath, and then I often feel very hungry around 4am, so I'll go into Soho and have a meal somewhere like Balans. That's what I love about living here - there's always life around me.

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 think there is a total equality for me between painting a literary figure or Kate Moss or my Mum or a dog or a bird. To me, they are all absolutely equal.

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 will look through 200 photographs of Kate Moss and there will be just one that I connect with for some reason, maybe because of the composition or something in the eye... Something touches me and I know I have to paint it, in the way a child knows it wants something.

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