I'm so excited to be working on Doctor Who as it's such a big and important part of British Culture. I can't wait to meet the cast and crew and start filming, especially as we'll be shooting not too far from my home town.

You know sometimes when you're in a really bad mood and you're not sure why? That's how I get sometimes.

Basically, me and Ed Sheeran are kind of Twitter friends - well, I say that. He probably just thinks I'm weird.

I get a lot of fan mail and stuff, and usually it's for me to sign stuff.

I watch vlogs on YouTube. I watch Jenna Marbles a lot - I think she's really funny - and a lady called Daily Grace.

I'm sorry; I ruin people's interviews because I just talk about rubbish.

I think people think I'm a lot younger than I am because of how I look on screen.
