I'm a classical singer, not a saint. I've never claimed to be that good.
I think people were shocked when it came out that I did drugs in my youth, but the thing is, if I was a pop artist and had talked about it I'm pretty sure no one would have batted an eyelid.
All artists want to do well in America, that's a given. But I didn't do Dancing With The Stars because I wanted to take over the world. It has made me more famous, though – it has an audience of 25 million – but when I walk down the street in LA people say: "Hey, you're that dancer!" They don't even realise I sing.
Heartbreak sucks. I can't describe it except to say that at the beginning of this year [just after Jenkins announced her split from her then fiancé, TV presenter Gethin Jones] I didn't think I would laugh again. But slowly and with some help from my friends, I've put myself back together again.
2012 was the year I saw Twitter as a negative [Jenkins was falsely accused on Twitter of having an affair with David Beckham and has had fake accounts opened in her name]. More people need to realise that not everything they read is true and that internet trolls are a real problem.
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.
Record labels always have a criteria in mind. When the people who signed me found out I was Welsh, that was a little tick. When I told them I was a teacher they said: "Ooh, we like that. That's nice." I'm not naive enough to think that I was signed for my voice and that was it.
Everything in my career is my decision – every picture, every outfit. You get one chance at this, and I never saw myself as being a puppet.
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.
They say grief brings people together but when my dad died we didn't speak about it as a family at all. I was angry he had been taken away from us and I couldn't see how talking to my mum and sister about it could be productive.
If someone's going to do the dirty on me, they'll do it. I can't be constantly worrying about it.
My future is buying a house in Wales near the sea, taking a break and having a family. It's where I see myself, and if I let that pass me by I'll be disappointed.
Jenkins's album This Is Christmas is out now on Warner Bros Records. The Katherine Jenkins Christmas Show finishes in Gateshead on 21 December
