I genuinely believed no one would want to marry me. I am difficult to live with. I'm selfish, quite weird and I need time on my own to think - and then I work all night long. That is difficult for someone to deal with. And it would drive me mad - I could never be my own girlfriend!

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

What I'm interested in watching is to make sure that they give the right advice now to the contestants who are going forward because, you know, it's one thing just to criticize but you've got to also give, you know, good advice which is going to help them. Overall, I think they're a good panel.

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

You have an advantage if you win. I always think it's best to be remembered as a winner rather than as the runner-up. It's definitely more fun getting the gold than it is the silver.

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.

You don't go into anything contemplating failure, because if you did, you wouldn't make it.
