David Tennant (10th Doctor) married Georgia Moffett (the 10th Doctor’s daughter in the episode “The Doctor’s Daughter”), who is the daughter of Peter Davison (5th Doctor) and they had a daughter. So the Doctor’s daughter played the Doctor’s daughter in “The Doctor’s Daughter” and then married the Doctor and had the Doctor’s daughter.
David Tennant & his wife Georgia Moffett. David's biggest acting dream that had been with him ever since he was 3, was to be the Doctor on his favorite show, Doctor Who. Not only was he able to do that, (and become one of the most beloved Doctors of the entire series) but he also got to marry his Idol's daughter. :)
Once upon a time there was a girl named Georgia Moffett, and her father was the Fifth Doctor. Then she grew up and played...herself...kinda...in The Doctor's Daughter, as Ten's daughter. Only she ended up marrying the Tenth Doctor aka David Tennant, and now they have a baby daughter. Which makes their baby...um...the Doctor's Daughter. The Ultimate Whovian, I guess. :D woah did not know this!
This is hilarious, but I think it is endlessly weird and romantic that they are together. :) (this woman is the actual real life daughter of the actor who played the fifth doctor, and married to david tennant, who played the tenth doctor... she also acted in a one off role where she played the tenth doctor's daughter)
