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

Being different is good; embrace it.

Normally if I go to one of these things I'm in and out in five minutes, but at Pride of Britain I stay to the end. It's a fantastic show. But it's incredibly hard on the night when you meet all the kids and hear their stories. They do get to you.

If I said to most of the people who auditioned, 'Good job, awesome, well done,' it would have made me actually look and feel ridiculous. It's quite obvious most of the people who turned up for this audition were hopeless.

They understand what their market is and who they should be selling records to, and most importantly, they know the kind of artist that they want to be, but they have to do it themselves. You don't want a 13-year-old singing some awful song from a musical.

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.
