The Daily Star reported that Georgis Moffat will be playing the dotors daughter, they said this:
DOCTOR Who gets a massive shock when discovers he has a daughter. The Time Lord is stunned after he lands back on Earth and meets a girl who claims he is her dad.
But all is not what it seems and the Doc eventually finds out his "daughter" has been created by aliens. They hatched a sinister plot to nick his DNA without him knowing. And, using his genes, they made the young woman themselves.
In a clever bit of casting, Georgia Moffett, 23, will play the Time Lord's girl. She just happens to be the real life daughter of former Doctor Who Peter Davison, 56. A source said "It's an amazing signing."
Show bosses are lining up some sensational storylines for the BBC sci fi show - back this spring. They include a showdown with the Daleks and their evil creator Davros.
