Children should be able to live a life free from bullying and harassment and it is time that we all took a stand against this.

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.

Yes. I do about 70 shows a year, in the past year I've been to Italy, Australia, Japan, China, just about everywhere. I do it because I love singing. The money is a bonus.

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'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!

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.

Marilyn Monroe was supposedly a size 16, which is probably why I love her style; it suits me better.
