If I went to a psychiatrist, it would be a long session. I've always thought that I do have a number of issues that probably need dealing with, because I am quite odd in some ways.

I've spent hundreds of thousands of pounds on the very best security and I can assure you my homes are as safe as the Bank of England.

My advice would be if you want to pursue a career in the music business, don't.

My heart, my lungs, my blood - they've all been checked. I remember one of the doctors almost being disappointed when he showed me the results because he couldn't wait to tell me what smoking was doing to me. But there was nothing there.

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.

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 get very anti-social, depressed and irritable with people. I don't have time for them. I can't make phone calls and stuff. I just sit on my own for days.
