I'm a Cancerian, the typical crab with the tough outer shell and the soft bit in the middle. I don't think I'll ever come to terms with people being unnecessarily nasty, but I can take it if someone doesn't like my music - I'm not everyone's cup of tea.

Beatbullying's 'The Big March 2012' is such a brilliant campaign and I am very proud to be a part of it. I have been a victim of cyber bullying myself and I know firsthand just how hurtful it can be. People think that they can hide behind computers and send nasty and hurtful comments to people, and this is wrong.

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.

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.'

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.'
