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!

Confidence is one of the sexiest things.

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.

At the weekend, one of the paparazzi left their lunch box filled with half-eaten pasta salad on my doorstep: it was like a little warning, you know? 'We have been here.'

I'm over the moon to be involved in the 'Doctor Who' Christmas special. I can't quite believe it as it's a part of the family tradition at the Jenkins household. I heard the news that I got the role on my 30th birthday and it was the best birthday present ever.

I've only ever wanted to be a singer; I never wanted to be famous.

People see you sing in a certain way, in a long dress, and you are put on a pedestal like you have never made a mistake in your life.
