The YouTuber-turned-boxer accused Hearn of having American judge Glenn Feldman on the Matchroom Boxing payroll following his scoring of Katie Taylor and Anthony Joshua’s respective clashes with Amanda Serrano and Oleksandr Usyk.
And the allegation has prompted Hearn to take legal action against the social media superstar.
Matchroom have sued the younger Paul brother for making an “outrageously false and baseless allegation” that has damaged their reputation.
Hearn is suing The Problem Child for defamation and damages upwards of £92m ($100m) for the “outlandishly false” accusation made in an interview earlier this month.
Matchroom Attorney Frank Salzano said: “Both legally and ethically there is a clear line separating opinion from defamatory lies.

“Jake Paul knows that, and he purposely crossed that line when he wrongly accused Matchroom Boxing and Eddie Hearn of fixing fights.
“Nonetheless he was still given an opportunity to retract his defamatory statements and refused to.
“Now he will face the legal consequences of his actions as Matchroom and Mr. Hearn will be seeking damages in well excess of $100 million given the value and goodwill attached to the Matchroom business and the harmful nature of Mr. Paul’s comments.”
Paul, 25, has found himself in legal hot water for saying: “Glenn Feldman shows up in Saudi and scores Anthony Joshua to win the fight when everyone who watched the fight said it was not a split decision.
