In Doctor Who you kissed Matt Smith and in Emmerdale you kissed Charley Webb (Debbie Dingle), which kiss raised more eyebrows?

Probably the one with the Doctor because a lot of people said, “he’s married!” [It was recently revealed the Doctor was married to River Song.] The other was good, in that it was teenagers exploring their sexuality but with Doctor Who they were like, “who is this new girl snogging the Doctor?”

Your boyfriend is in Game of Thrones [as Robb Stark], do you watch each other’s shows or is there a sci-fi ban in the house?

I’m a massive Game Of Thrones fan, and I’m going to continue watching it now he’s [left] and yeah, he’s a really big Doctor Who fan, which is lucky. We like each others’ shows.

What else do you watch?

We’re watching The Tunnel at the moment, The Newsroom and I’ve just started to watch The West Wing and Homeland - there's a lot we're into.

Your fan base is very vocal. Have you had any unusual encounters?

People shout, “Where’s your Tardis?!” a lot. And there’s this thing called cosplay, where people dress up as your character. I have been sat in a restaurant and people have asked for a picture then I’ve realised they are full on dressed as my character.

Have you made it to a convention?

I went to Comic-Con in San Diego this summer and we did a panel to 8,000 fans. Comic-Con is like Coachella but with super heroes. It’s where True Blood, Game Of Thrones and all these shows do panel talks and their fans go and dress up for the weekend. It’s surreal, the whole city gets taken over by Batman and Spiderman. Driving round we would see people dressed as me and Matt. I thought I would be overwhelmed but to see such an amazing reaction was humbling.

The Day Of The Doctor is on BBC1 at 7.30pm on 23 November in 2D and 3D.
