It's fair to say there's no love lost between Harry Potter author JK Rowling and Labour Party leader Jeremy Corbyn.
Just look at this tweet from 2016...
Â
Or her recent pre-Christmas thread which parodied Corbyn and his supporters and highlighted antisemitism on the left.
Â
Now the author has taken to Twitter to criticise Momentum, the left-wing campaign group that was founded following Corbyn's successful campaign to lead the Labour Party.
Quote tweeting a tweet from Momentum's account, she said she wishes that the group's Twitter is a parody account.
Â
But Momentum fired back with a sarcastic put down of its own...
Â
Unsurprisingly, Twitter was divided, with some users siding with Rowling...
Â
But most replies seemed to side with Momentum as it wasn't clear exactly what Rowling took issue with in their original tweet. Many even praised their social media skills.
Â
One thing's for sure, there's probably a cell in Azkaban with Momentum's name on it.
