2012 was the year I saw Twitter as a negative. More people need to realise that not everything they read is true and that Internet trolls are a real problem.

I have a long fuse.

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!

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.

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’ve only ever wanted to be a singer; I never wanted to be famous.

I can’t leave the studio until everything is as it should be. And I can’t put a record out unless I am completely happy with it. I never want to be at a signing and hear my album playing and think, ‘Oh no, I could have done that top note better.’

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.’

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.

Being a question on ‘The Weakest Link,’ that was quite a moment.
