You learn your lessons from the mistakes you make, not the things you achieve.

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'd love to play Carmen - it's the perfect mezzo role.

I was such a geek in school.

I have to believe that I know what's best for me. For instance, I choose all my songs. I never record anything I don't want to record. No one tells me what concerts to do.

I go home and don't get treated any differently. People have known me all my life and are interested and very supportive but because they have known me forever I don't get any diva treatment. My mum still tells me off if I haven't loaded the dishwasher for her.

I'm not naturally a person that wants to exercise, but I find running is something I can do wherever I am in the world.
