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.

I was such a geek in school.

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.

I sing a mixture of everything from opera, folk music, Broadway. It's a mix of 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.
