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.

More than anyone, I am aware of the preconceptions. I was a Spice Girl. I'm married to a footballer.

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.

I'm very realistic. I know my boundaries - I know what I'm good at and what I'm not good at.

I was very obsessed. I mean, I could tell you the fat content and the calorie content in absolutely anything.

[My boys] bloody well will work. Same as myself, same as David. They're not going to be the kinds of kids that just hang about. I want them to be able to fulfill their passions, but I think it's important that the children grow up and have respect for themselves.

I am eating more. I think you do eat more when you're working out. And you want to eat healthily, so it's good all round.
