Conor McGregor was challenged by Liver King to a disgusting raw liver-eating contest after calling out a social media star

CONOR McGREGOR was challenged to a disgusting raw liver eating contest by “Liver King”.

The social media star – real name Brian Johnson – who shot to fame for his raw-organ meat diet and physique.

He is believed to weigh around 13 stone on a diet of animal brain and lungs and even has a Liver Queen wife.

So McGregor faced comparisons online after posting pictures looking bulked up ahead of his UFC return.

But he responded: “Who? I eat the liver with shots not forks. Ball of the foot, heel of the foot, fist, elbow, you name it.

“Even the butt of the head on the sly I dig them in. Production sees nothin till highlights, and even then only the next day.

“Motherf***** I destroy liver. I’m King, period.”

But this drew a response from Liver King, who called out McGregor, 34, in a reaction video.

He takes three shots, before taking a bite out of a BONE and raw meat.

Liver King said: “I’d like to take this chance to apologise to absolutely f***ing nobody.

“Last time I checked, the name is Liver King because liver is king! You should know this crown is mother****ing bolted to Liver King’s head.

“It’s going to take one helluva savage to remove it. Nobody, and I mean, nobody, attacks Liver with such ferocity (at breakfast, lunch and dinner).

“If you’re game to try, by all means, practice what you preach @thenotoriousmma. Until then, you can call me Liver King.”
