JK Rowling and Piers Morgan spend a lot of time arguing
JK Rowling and Piers Morgan have been showing the world that they really don't get along.
The Harry Potter creator and Good Morning Britain presenter have been publicly arguing on Twitter.
It started as a simple back and forth after Piers Morgan was sworn at on a US chat show.
It's led to surprising revelations about Morgan family tattoos - and a Harry Potter book being painstakingly Tweeted, line by line.
It kicked off when JK Rowling shared a video of Piers Morgan being sworn at on a US chat show on Friday night.
Morgan then claimed he'd "never read a single word" of Harry Potter.
Rowling hit back, referencing Piers Morgan's support for US President Donald Trump.
Others were about book sale stats, of course.
Piers Morgan's son, Spencer, clearly felt caught in the middle - especially as he's got a Harry Potter tattoo.
Harry Potter fan Simon Key, who runs a book shop in London, decided to get involved too and has been tweeting Piers Morgan the entire text from the Philosopher's Stone.
Since he began, the book shop owner has made some progress and is currently up to quote number 176 out of an estimated 32,567.
