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'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.

The ability to suspend reality and go into a make-believe world can be really, really difficult if there's something really big going on.

I pay our nanny more than Im earning.

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.

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 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.
