I've been lucky that I've performed with a lot of the classical people I've wanted to work with so I'd like to do something that people didn't see coming. Like Madonna, or being Welsh - the Tom Jones thing. Or somebody suggested N-Dubz - that would be brilliant!

I really see myself as a homegirl. Wales is my first home. London is my second home - I've been there 14 years now.

From as young as I can remember, I always wanted to be a singer... My mum taught me 'Going Down the Garden to Eat Worms' for a competition when I was about 4.

I would absolutely, definitely never sell my wedding pictures to a magazine. I'd like it to be a special day, not a photo shoot. And once you've done that, your marriage becomes everybody else's business.

I was such a geek in school.

I can't leave the studio until everything is as it should be. And I can't put a record out unless I am completely happy with it. I never want to be at a signing and hear my album playing and think, 'Oh no, I could have done that top note better.'

My idol was Marilyn Monroe, who was a size 16, I think, and curvy in all the right places. I will never be stick thin. I remember a shoot where I had to get into these tiny hot pants, and I thought, 'God, I wish I hadn't eaten.'
