"Doctor Who" is welcoming a new face on board the TARDIS. Jenna-Louise Coleman is joining the popular BBC series during Season 7 of "Doctor Who." She's replacing Karen Gillan and Arthur Darvill, whose characters Amy Pond and Rory Williams will have a "heartbreaking departure."

BBC America has released the first official photo of Coleman and Smith on the official "Doctor Who" Tumblr. Coleman's role was announced in March 2012.

"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," Coleman said in a statement.

Executive producer and lead "Doctor Who" writer Steven Moffat said when the producers saw Coleman and Smith together, they knew she was right for the part. "She's funny and clever and exactly mad enough to step on board the TARDIS," he said in a statement in March.

"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," Moffat said. "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 the Time Lord ever encounters. Even by the Doctor's standards, this isn't your usual boy meets girl."

Coleman joins a long line of famous faces who have traveled alongside the Doctor since the series was rebooted in 2005. Billie Piper, Freema Agyeman and Catherine Tate have all co-starred on the series as the Doctor's companion.
