I have started smiling! I've mastered this smirk; it's a smile that isn't a smile.

I think as I have got older, I have got a bit more relaxed, although you might not think that if you heard me screaming at my kids.

You'd have thought they'd have been on about Sir Elton John, and the fantastic goals David has scored which have got us through to the World Cup. But what they were really interested in was that I was holding a bag that had 'Sex' written on it. It's quite bizarre.

I wake up every morning and I feel like I'm juggling glass balls. I live in Los Angeles, my business is run out of London, and most evenings I'm cuddled up in front of Skype, in my dressing gown, speaking with my studio in London. I travel a lot, my team travel a lot, but I wouldn't have it any other way.

I was never going to give Mariah Carey any competition.

I take care of myself. I work out every day. I eat healthy. But I like to have fun too.

I've been in the public eye for about 15 or 16 years and I'm very aware that fame is not a given. I have to maintain it. It's not just something that will always be there.
