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 would absolutely, definitely never sell my wedding pictures to a magazine. I'd like it to be a special day, not a photo shoot. And once you've done that, your marriage becomes everybody else's business.

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

I do not understand where the idea came from that opera is only for privileged people, I am as happy singing before 70,000 people at the Millennium Stadium, as I am in front of a few hundred in a small concert hall.

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.

I'm launching my own festival in South Wales. It's something I've wanted to do for a long time. It's going to be held at Margam Park, because I wanted the venue to be as close to my home as possible.

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.
