Jenna-Louise Coleman has landed the role of the Time Lord's new companion in Doctor Who
, the BBC has confirmed.
Producer Steven Moffat announced the actress will replace Karen Gillan's character Amy Pond when she leaves the show in the next series.
The star said: "I am beyond excited. I can't wait to get cracking."
Coleman, who will make her first appearance in the Christmas special, added that she is a "huge fan" of the show.
"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," Moffat said.
