I like to know why a video has suddenly gone viral, why a song has broken, why a TV show is suddenly rating out of pattern... I'm pretty good at understanding why things are becoming popular.

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

I think if you're an unhappy person, you're always going to be an unhappy person. You're probably going to be less unhappy if your business is doing well, if I'm being honest.

I have very good advice to give to kids this age, which is, you shouldn't listen to your mum or dad and you just have to work it out for yourself. And the reason I've taken the age range down this year, and I never would have done it 10 years ago, is what I've seen with the success of Willow Smith. You don't have to be so cutesy anymore.

I work out three or four times a week, I have Botox, take tons of vitamins and vitamin infusions - if you believe that these things work, you will feel better.

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

What luxury would I take to a desert island? A mirror. It's true. I'd miss me.
