TV has lost a lot of its self-confidence as its power has been eroded by the internet.

I don't have a fear factor. Well, not much of one. And I'm willing to risk quite a lot - as a comedian, you're always risking a lot. You're risking failure, especially if you're improvising and going on TV shows trying to make comedy out of thin air. That is quite a risky business.

I don't get recognized much, and am very happy with that. The fans I have met have all been delightful.

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'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.

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.
