Doctor Who: 13 Cool Details Steven Moffat Just Revealed About The Girl In The Fireplace
2. Reinette Is Distantly Related To Donna Noble
Another fact about the real-life Madame de Pompadour is that her mother was called Madeleine de la Motte, and according to Davies, this means that there's a connection between her, and the Doctor's Series 4 companion, Donna Noble.
Donna's granddad is, of course, the lovable Wilfred Mott, who appeared in quite a few episodes towards the end of Tennant's run.
And his last name, "Mott"? That means he's a distant ancestor of Madeleine de la Motte, and thus - as tweeted out by Davies - Wilfred and Donna are ever-so-slightly related to Madame de Pompadour.
Sure, he's joking around a little, but this is too good to not be considered canon. Davies has spoken!
