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!
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 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'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 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 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 have such happy memories of performing in a choir and I don't think I'd have got where I am today without all that experience. So my advice to young singers is to either join your school or church's choir or find one in your local area. Choral music at any level teaches you so much about musicianship and blending your voice.
I have never called myself an opera singer. Other people do, but I always call myself a classical singer. I'd love to do opera, but I'm still too young and I don't want to do it until I'm ready. I realise that when I do that it's going to be... up for discussion, shall we say, so I want to get it right.
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.
I get 'voluptuous' a lot, or 'shapely,' but the fact is that as you get older you learn to embrace your body type. I wasn't able to do that until I was at least 23.
Being a question on 'The Weakest Link,' that was quite a moment.
I'm still a Welsh girl at heart so I'm staying in the U.K. for the Olympics, it's such an exciting time for Britain so it's amazing to be a part of it.
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!
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.
