In a surprise move, Steven Moffat and the BBC have declared that Jenna-Louise Coleman will be portraying the new companion for Matt Smith‘s Eleventh Doctor, beginning with the Doctor Who Christmas Special at the end of 2012.

You can watch an interview Doctor Who TV did with Coleman about the news at the bottom of this post.

Many enthusiasts and speculators had previously believed the announcement would be kept tight-lipped until before the Christmas Special this year, so the BBC news about the new companion came as a big revelation to Whovians across the world.
