I get very anti-social, depressed and irritable with people. I don't have time for them. I can't make phone calls and stuff. I just sit on my own for days.

The only people with power today are the audience. And that is increasing with Twitter, Facebook, and everything else. We cater to their likes and dislikes, and you ignore that at your peril.

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

Whether they run a record company or a grocery store, every boss will tell you you're in big trouble if you're borrowing more than you can ever afford to pay back. Delaying the pain for future generations is suicidal. We've got to start getting the deficit down right now, not next year.

I can't stand stage mothers. It doesn't work. You definitely feel that with the new generation of pop stars right now they've all managed to work it out for themselves. You have to have confidence in that. When you're young, you know your market better than I will. I love having young people on the show because I can learn from them.

It simply works. You do it twice a year. Who cares? And it balances my smoking and drinking.

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.
