At the outset of the women's Wimbledon final, in which Serena Williams beat Garbine Muguruza to victory, Queen of the Wold J.K. Rowling declared herself #TeamSerena.
I'm #TeamSerena today, because you don't meet many super-talented people nicer than she is. Go @serenawilliams!
She was so into the match, it all got a bit When Harry Met Sally.
YES YES YES! #SerenaWilliams
She still had plenty of love for Muguruza, mind.
Muguruza is unbelievable. 21 years old! #Wimbledon2015
But then it was back to the Serena excitement.
I just yelled like I got hit by that ball. #Wimbledon2015
She declared that history was made.
Tennis history is made! #QueenOfCentreCourt @serenawilliams
And quite rightly highlighted what a wonderful role-model Serena Williams is.
#SerenaSlam! I love her. What an athlete, what a role model, what a woman!
Even a post-Harry Potter novel is no match for Serena's A-game.
The match is still technically going on, right? Because otherwise I've got to go back to copy edits.
But best of all, when some troll said Serena looked like a man, J.K. Rowling put him right in his place.
.@diegtristan8 "she is built like a man". Yeah, my husband looks just like this in a dress. You're an idiot.
