One thing I've learnt is you should never fight it. They're natural emotions and when you try and bottle everything up, that's what can make you depressed. Luckily I have fantastic memories [about my parents] and they really help.

I think of stress as the creator of cancer and heart attacks, like a tiny little ball you feed. I believe that one of the reasons I've never got ill is that I'm not stressed.

I have seen that the American Dream is a reality - and I would love to feel the British Dream is also a reality. To enable that, we have to bring back some common sense and encourage family values, a proper sense of justice and make people believe they have a decent chance to build a business or career for themselves. I see this moment as a fantastic opportunity to restore this, because I believe Britain Has Talent.

Everyone who turns up on 'X Factor' does it because a door has been closed to them at some time in their lives, and this is the only shot they have got.

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 hate belongings. I hate clutter. It really bothers me because I can't think properly. If you've got distractions in front of you, your mind goes nuts.
