I'm worried about losing my hair. I think if I lost my hair, I'd lose a lot of parts. And I don't want to get fat. I'm always worried about that.

To be able to play Jack Kerouac or Sal Paradise, it's mad to me.

Friday is my night for letting my hair down, and once a month a group of my old male friends will come down and stay at our house in Hampshire.

I pay our nanny more than Im earning.

I did a bit of modeling before I took up acting, and I was up for this big campaign - I can't remember which designer - and all these execs were looking at my portfolio. Then one said: 'We'd like to use you, but can you come back next year when you've lost this.' And he tapped the underside of his chin.

I get very few nasty letters. A few from people who disapprove of the fact that I'm getting naked on television yet again. I don't know why - I suppose they don't like the idea that I'm doing that while I'm married with children.

I've always taken a lot of exercise - I get a bit depressed if I don't. In terms of food, I'm a bit of a grazer.
