When you are doing endurance swimming you just need to take in as many carbs as possible to put on as much weight as you can. Basically you can eat whatever you want, which can be quite fun. Everything is guilt-free.

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 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 can't see why anyone would want to be in politics because you get so much criticism.

I think all those rules are boring. About what people can and can't wear. Surely everyone should be able to wear whatever they like?

I just want to be happy, have kids, enjoy my life, help others and create some good work.

American culture is kind of an international culture, isn't it? British culture is a bit more unique. I think funny things are sort of funny around the world, really.
