When I was about 14 I remember thinking when it came to proposing to my future girlfriend, I'd make a CD with all her favourite songs and a message that said, "Will you marry me?" Shows you what a romantic I was. No one listens to CDs any more. It's all about iTunes.

Artists take on an alias that's suitable for their style of music. Everyone had a nickname when they were younger.

Hopefully, young people will see that you can be young and make the sacrifices to follow your dreams.

I'm a bit of a mummy's boy.

I met Ellie Goulding at the BRITs. She's lovely. I've got a lot of time for her. I gave her congratulations and whatnot and she let me hold her BRIT. That was amazing - once I'd touched one for the first time, I said 'This cannot be the last time I touch a BRIT.

I really want to work with Adele, I think she's amazing. Lykke Li as well. I love them both. I'd also like to work with The Script. I met them in Australia and we just got on like a house on fire.

I didn't take it seriously myself at the time, but now all of my old teachers are supportive. Even my principal - I sold out the O2 Arena in London, and he came out to see me, which was really cool. I actually put a picture with him on my Instagram, and I think and he's wearing one of my snapbacks.
