It's no secret that Piers Morgan is a man who loves to argue.

His latest bone is with Harry Potterauthor J.K. Rowling and despite how much she has been eviscerating him on Twitter over the past few days, he unfortunately persists.

The feud continued today when Rowling shared an excerpt of a glowing review of her brilliance in Daily Mail's list of 100 British celebrities who matter.

"Just been sent this! Could the writer let me know who he is? I'd love to thank him!" Rowling wrote on Twitter.

Morgan re-tweeted the post with a snarky remark, further criticizing the author.

"Priceless #humblebrag BS," he wrote. "Nobody plays the celebrity game more abusively or ruthlessly than you, Ms. 'Intensely Private Billionaire.'"

Of course, what Morgan seems not to grasp, is that he wrote the damn thing to begin with. Back in 2010, he praised her for her down-to-Earth manner in the spotlight.

Folks were delighted and extremely quick point out to Morgan that he was the author behind the piece.

It took Morgan three hours, however, to denounce the oversight.

Not surprisingly, people aren't necessarily buying it.

Rowling has yet to respond to the comment, but the fact that it currently is her pinned tweet speaks volumes.
