Fifty Shades author E.L James is the latest celeb to tackle Piers Morgan

Piers Morgan has been angering quite a few bibliophiles on Twitter in recent weeks. 

Piers has been in a battle of 180 characters with JK Rowling for quite a while, as the two have had some political disagreements.

In the midst of the war of words, Harry Potter fans have begun tweeting Piers Morgan the contents of the Harry Potter and the Philosophers Stone novel in it's entirety, and the journalist has had it up to here with the Hogwarts-themed tweets.

Seeking some respite, Piers tweeted Fifty Shades of Grey author E.L James, asking for a quote from her from one of her popular erotic novels. 

E.L James proceeded to perfectly troll the journalist, by tweeting back a line from Harry Potter and the Chamber of Secrets.

Clearly missing the joke, Piers responded to the perceived dig with: "Fortunately none of your characters would ever risk over-exposure…"

The quote is, of course, not even from Fifty Shades of Grey, but is in fact from a scene in Harry Potter and the Chamber of Secrets between Defence Against the Dark Arts Professor Gilderoy Lockhart and Harry Potter.

Clearly E.L James has JK Rowling's back in this battle. 

The Harry Potter author also made a pretty funny joke at Piers's expense on Valentine's Day, as she posted a gushing review about her contribution to children's literacy.

While JK Rowling feigned the anonymity of the post for the sake of satire, it was quickly revealed on Twitter that it was Piers Morgan himself who had written the piece a few years ago.

"I bet he's having a monumental trumpesque meltdown," replied one follower. 

It might be time for Piers to take a little Twitter break now, no?
