Spoiler:

Jenna-Louise Coleman has been announced as the new Doctor Who companion.



The Titanic actress is confirmed to be replacing Karen Gillan (Amy Pond) as the assistant to Matt Smith's Time Lord in the BBC sci-fi show's seventh series. Coleman's debut episode will air at Christmas.

Speaking at BBC's Broadcasting house this morning, she said that she was a "huge fan of the show", commenting: "I'm beyond excited, I can't wait to get cracking; working alongside Matt I know is going to be enormous fun and a huge adventure.

"Matt Smith did my audition with me. It was fun and I felt like we were in it together."

Coleman also revealed that her personal favourite companions were Billie Piper and Karen Gillan.

Showrunner Steven Moffat said: "It always seems impossible when you start casting these parts, but when we saw Matt and Jenna together, we knew we had our girl. She's funny and clever and exactly mad enough to step on board the TARDIS.

"It's not often the Doctor meets someone who can talk even faster than he does, but it's about to happen. Jenna is going to lead him his merriest dance yet. And that's all you're getting for now. Who she's playing, how the Doctor meets her, and even where he finds her, are all part of one of the biggest mysteries for the Time Lord ever."

It is known that they will leave part way through series seven in a "heartbreaking end", and Gillan has teased that her exit will have a "strong impact".

She also described her final Doctor Who storyline as a "damn good" one that will see Amy go out "on a high".
