Piers Morgan Tells JK Rowling to 'Shut Up' on Fox News
11 Best Netflix Movies for Singles on Valentine's Day

Piers Morgan is continuing to stoke the fire in an ongoing feud with "Harry Potter" author J.K. Rowling.

“She’s a serial loser," the former CNN host told Tucker Carlson on Fox News Monday night. "The more that J.K. Rowling has screamed at people to vote in a certain way, the more her people have lost."

He proceeded to cite three examples: Not backing the winning candidate in the last UK election, opposing Brexit, and supporting Hillary Clinton.

“Just go write about Hogwarts, wizards, whatever they are. I’ve never read a word of Harry Potter. Just go and immerse yourself in the world of Muggles or whatever they are, and shut up.”

Oof. Rowling has yet to respond, but we expect a sharp response in 140 characters or less on Twitter any minute now.

The two began sparring earlier this month after Morgan, an editor and columnist for the Daily Mail, battled comedian Jim Jefferies on HBO's "Real Time with Bill Maher.

"This is what you do, Piers. You say, 'He hasn't done this, he hasn't done that, he's not going to do all these things,'" Jefferies said. "Give him a f--king chance, mate. Hitler didn't kill the Jews on the first day, he worked up to it, mate."

Morgan told Carlson Monday night that he finds the comparisons of President Donald Trump to Adolf Hitler "incredibly offensive," because "it diminishes the scale and importance and horror of what Hitler did."

“Donald Trump, to my knowledge, has not murdered anybody," Morgan said. "But of course you try and say this, and if you’re not prepared now in the liberal world to say that he’s the new Hitler and you’re not prepared to say every Muslim is banned from the country, you yourself then become the Devil and that’s what happened to me.”
