In a move that will have them weeping in the aisles, it's been announced that former 'Doctor Who' star David Tennant is getting married. And, according to The Daily Mail, he's marrying ... his daughter.

Yes, in a strange way of keeping it all in the 'Doctor Who' family, Tennant's announced his engagement to actress Georgia Moffett. 'Who' fans will remember her from a guest spot on a 2008 episode ('The Doctor's Daughter') in which she played Tennant's feisty onscreen daughter Jenny.

And that's not the only 'Who' connection: Georgia's dad is none other than actor Peter Davison, who also used to be Doctor Who. He played the fifth Doctor from 1981-4 and was last seen in the role in 2007 when he appeared with the tenth Doctor -- a.k.a. David Tennant -- in a charity episode on British TV.
