Piers Morgan just SLAMMED JK Rowling, but the joke was on HIM

We all know if you want to see famous people flaunting their wares, you rock up to Instagram.

But if you want to see famous people brawl it out amongst each other, you head right on over to Twitter.

And if there are two people capable of attracting a crowd within the Twitosphere, it's JK Rowling and Piers Morgan.

Considering that there's no love lost between the author and the Britain's Got Talent judge, JK decided to set a trap for the journalist, and it went down a storm among her followers.

Sharing a screenshot of a very flattering article which was penned abour her, JK wrote: "Just been sent this! Could the writer let me know who he is? I'd love to thank him. #Valentine's."

Wasting no time calling JK out for sharing the complimentary piece, Piers retweeted the author, writing: "Priceless #humblebrag BS."

"Nobody plays the celebrity game more abusively or ruthlessly than you, Ms Intensively Private Billionaire'.

And the kicker?

Piers himself had written the gushing prose way back in 2010… and there was no way in hell Twitter was going to let this one go.

"Hook, like and sinker, " wrote one while another added: "You do realise you wrote this and that's the joke?"

"I don't think it has quite dawned on him that he wrote this sycophantic tripe for the mail 6 years ago," remarked another

Piers, it might be time to admit defeat on this one.
