I'd say the most dangerous thing I've ever done is probably bungee jumping in Thailand...

If you only ever heard Lady Gaga, she's the most boring singer in the world.

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.

I got good advice once. Someone said to me: 'Live in your money rather than look at it.

I do see a big difference in the American work ethic compared to the British work ethic in a lot of artists.

I met someone the other night who's 28 years old, and he hasn't worked a day since he left college because he's pursuing a dream he'll never, ever realize: He thinks he's a great singer. Actually, he's crap.

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.
