In Heaven, I believe my dad is somewhere doing something nice. I feel I've been too lucky to travel this far without somebody guiding me.

I did once shatter a chandelier. I was singing with my college choir in Wales. I was the soloist and I hit the high note and there was this massive bang and all this glass came down from the ceiling. I'd like that to be my party trick if I can perfect it.

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 have to believe that I know what's best for me. For instance, I choose all my songs. I never record anything I don't want to record. No one tells me what concerts to do.

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 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.'
