I really see myself as a homegirl. Wales is my first home. London is my second home - I've been there 14 years now.

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.

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 am fussy, about my diet and straining my voice. I know, sounds a bit over the top. But I'm not as bad as I used to be. These days I don't drink alcohol for five days before a show - very dehydrating for the vocal cords, and all that acid reflux. I used to ban it for a fortnight. Nightmare.

People perceive opera and classical as elitist - I disagree. I've always tried to mix the two, make it more accessible.

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.'

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.
