I do a couple of hundred press-ups a day but I haven't been to a gym in years.

One thing I've learnt is you should never fight it. They're natural emotions and when you try and bottle everything up, that's what can make you depressed. Luckily I have fantastic memories [about my parents] and they really help.

I thought the first two seasons of America's Got Talent were good. I think this one is the best one by a mile because they - you see the difference this year, I think, with the crowd being effectively the fourth judge. But most importantly, I think that these shows have to have a relevance because if you're not finding stars at the back of these shows - whether it's Idol or Got Talent - they're a complete waste of time.

Good is not enough. You've got to be great.

Talking to celebrities is too much effort. They all think the same.

Money brings you security and choice. You can make decisions in a different way if you have a lot of money. But when you have nothing, you have a naivety, and a more fearless attitude because you have nothing to lose.

I love producing shows. And so when you're on a show where other people are making decisions you don't necessarily agree with it, after a while you start to feel like a passenger.
