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.

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

Praise a stranger with a few nice words and he becomes a stranger that calls you a friend.

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 sounded like someone who should be singing on a cruise ship. Halfway through your song, I wished the ship was sinking.

My own saying is: 'Create the hype, but don't ever believe it.'

The object of this competition is not to be mean to the losers but to find a winner. The process makes you mean because you get frustrated. Kids turn up unrehearsed, wearing the wrong clothes, singing out of tune and you can either say, "Good job" and patronize them or tell them the truth, and sometimes the truth is perceived as mean.
