Music should always be polarizing. What one person likes, somebody else hates. And I hate that kind of snobbery in pop music. The fact that so many people are getting upset over this one song is hysterical. And if people like it, that's great.

Thank God kids love following an artist. When you get a group who pop, it's the best thing in the world.

I don't mind competition at all. I mean, the record business is the most competitive business in the world, probably. So I'm used to that. In a weird way, it kind of makes you work harder.

I break up very well. I am a good breaker-upper.

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.

The secret of my success is that I make other people money. And, never, ever, be ashamed about trying to earn as much as possible for yourself, if the person you're working with is also making money. That's life!

I've always been petrified of working for a boss who I didn't like but who I was in fear of, because I wanted my salary.
