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 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.

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.

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 like to watch old films. Meet Me in St Louis, Cul-de-Sac and Buffalo 66 are some of my favourites.

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

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