When I was on stage with the Spice Girls, I thought people were there to see the other four and not me.

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 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.

We are still so close, David and I. We were at a party the other day at my mum's house and I was sitting on his lap. We're very affectionate. And I looked at him and thought after being married for 11 years! We were the only couple who were even near each other at that party. We're soul mates.

If you have a surreal life like I do, you've got to have fun along the way.

I consider all of my pieces to be investment pieces. A dress shouldn't be worn for one season - you should be able to wear it year after year.
