In case you didn't know already, Harry Potter author J.K. Rowling is a BIG fan of Strictly Come Dancing contestant Susan Calman. In fact, she's regularly tweeting her adoration for her ballroom dancing friend.
And last night (19 November) she was spotted in the audience of the Blackpool ballroom alongside Susan's wife to watch Susan and Kevin's superb Strictly Ballroom-inspired Paso Doble.
But that's not all, Rowling also bought with her an incredibly sweet gift for Susan - a cupcake decorated with three number 10 paddles.
'Bought you a present,' the author tweeted to Susan alongside a pic of the cupcake. 'Thanks gorgeous. Hold it up after I dance,' Susan tweeted back.
Viewers couldn't get enough of spotting the author in the audience, alongside other famous faces including Graham Norton, Peter Kay and Lenny Henry.

Unfortunately, the number 10 paddles were only seen on the cupcake, as Susan and Kevin saw themselves at the bottom of the judge's leaderboard.
Tune in tonight to Strictly Come Dancing: The Results on BBC One to see whether Susan and Kevin are through to the next round.
