I have such happy memories of performing in a choir and I don't think I'd have got where I am today without all that experience. So my advice to young singers is to either join your school or church's choir or find one in your local area. Choral music at any level teaches you so much about musicianship and blending your voice.

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 go home and don't get treated any differently. People have known me all my life and are interested and very supportive but because they have known me forever I don't get any diva treatment. My mum still tells me off if I haven't loaded the dishwasher for her.

With 'Believe' bringing really big success for me outside of the U.K. for the first time, it meant I have been touring around the world and that led to a gap from the studio. I really feel like the gap has done me the world of good. Throughout that time I was able to collect songs that I really loved.

When I dance, I forget everything else and just feel completely happy.

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.

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.'
