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.

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.

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

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.

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

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'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.
