I have a pathological fear of being on my own. When I'm with my own thoughts, I start to unravel myself, and I start to think really dark thoughts, self-destructive thoughts.

I was quite fat as a kid. And swimming is a sport you can enjoy whatever size you are. If you're fat, running is a pain. I'm not really built for running.

We sort of expect to see men in women's clothes. It's part of our culture. The key thing is, it has to be done quite badly.

When I want comfort food, I buy Maltesers. I like all chocolates, but especially those. You can eat them, and because they're so light, you can convince yourself that they are not actually that fattening.

My favourite restaurant of all time is Mildreds on London's Lexington Street. It's a little vegetarian restaurant and is really fun and healthy, too. It was the first place I went to in London and really liked. That was 20 years ago, and it is still my favourite.

I used to have a silk dressing gown an uncle bought in Japan and when I came downstairs in it, my dad used to call me Davinia. There was never embarrassment about that kind of thing. My sister used to dress me up a lot. She thought I was a little doll.

I've done panel shows, which I enjoy, and on those you're recording half-an-hour of TV and sometimes they film for two hours. But with 'Britain's Got Talent,' you're on camera for eight hours, with a large theatre audience watching - and in between you're being filmed for ITV2 as you eat your lunch.
