When I dance, I forget everything else and just feel completely happy.
I always want to give my best and do the best I can. I know when I have sung my best and when I haven't. There can be stresses and hassles with time travel and press attention. I just have to adapt and find a way of dealing with it.
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.
Growing up with my family gave me some of my best memories. I'd like to have a family of my own - slip away for a bit and do nothing but spend those early years with my children.
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'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!
My idol was Marilyn Monroe, who was a size 16, I think, and curvy in all the right places. I will never be stick thin. I remember a shoot where I had to get into these tiny hot pants, and I thought, 'God, I wish I hadn't eaten.'
I wasn't the best in my class at the Royal Academy. There was a really good soprano and baritone who were technically better and are doing really well in opera now. But I was definitely the best mezzo-soprano in my class, because I was the only one of those!
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'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.
I love to listen to pop music and I admire people who do that, but I don't think I would ever be a very good pop star. I always leave that singing voice for the shower! I wouldn't put it out in the world!
I'm a Cancerian, the typical crab with the tough outer shell and the soft bit in the middle. I don't think I'll ever come to terms with people being unnecessarily nasty, but I can take it if someone doesn't like my music - I'm not everyone's cup of tea.
If you love somebody, you love them. My parents had a 25-year age gap between them and my mum was the breadwinner, my dad the house husband. I'm a strong believer that a good relationship can work, whatever the situation.
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.
In Heaven, I believe my dad is somewhere doing something nice. I feel I've been too lucky to travel this far without somebody guiding me.
With all the hundreds of dresses and shoes I have, it would be an absolute crime if I don't have a little girl. I have a whole room at home filled with my stage wear.
