Davina McCall

Davina McCall provided the voice of the Davinadroid in TV: Bad Wolf. She is best known for hosting Big Brother. In March 2009 she co-hosted the BBC's Red Nose Day appeal for Comic Relief alongside David Tennant. She suffered the ignominy of being beaten by Tennant in a mock game of Mastermind in which he demonstrated knowledge of Doctor Who superior to her knowledge of Big Brother.
