Jake Paul has threatened to knock out UFC president Dana White if the pair next meet in Las Vegas.
Paul, who was cageside at recent Conor McGregor and Jorge Masvidal pay-per-view fights, has been at loggerheads with White for months.
The YouTube star has been fiercely critical of the UFC's pay structure while White has hit back at Paul for embellishing his pay-per-view figures.
And now Paul has claimed he wants to settle his beef with White in person.
"I think it [the feud with Dana White] ends with me running into him at a club in Vegas and me knocking him the f*** out," Paul said ahead of his clash with Tyron Woodley on Sunday.
"We go back and forth, at the end of the day," Paul explained. "He's always talking about me, I'm always talking about him.
"He's trying to discredit what I'm doing - one moment he loves Tyron Woodley and he's a five-time UFC champion and Dana White's saying, 'He's one of the greatest welterweights ever'
"And then, boom, 12 months later he sucks. Jake Paul's fighting him, blah blah blah. He's just trying to discredit anything that I do.
"Which, of course, that's what I would do if I was in his position. He's a smart guy."
White has questioned Paul's legitimacy as not only a fighter, but a pay-per-view draw, saying that the reported 1.5million buys that his fight with Ben Askren in April did were not accurate
“The numbers that you are hearing that they did are full of s***," White said earlier this year. "They are full of s***, okay? They didn’t pull those kinds of numbers at all. Not even f****** close.
“The numbers are there? Nah, I don’t know if the numbers are there."
Paul will take on the second former UFC star of his career on Sunday night when he faces ex-welterweight champ Woodley in his hometown of Cleveland, Ohio.
And despite being the bookies' favourite, White isn't so sure that Paul will be able to get the job done when the pair finally meet in the ring after months of build-up.
"I'd have to go with Woodley by knockout, White said on the Real Quick with Mike Swick podcast when asked for a prediction in June.
"Listen, man, Woodley should knock him out.
"But, again, the Tyron Woodley that you talk about, that was the champ, isn't the same f***ing guy he was four years ago."
Paul vs Woodley is reportedly trending towards being one of the biggest boxing events of the summer.
ESPN reported that pay-per-view buys are trending in a similar direction in the US to Floyd Mayweather's exhbition with Paul's older brother Logan, which topped one million in the US and earned both men an eight-figure pay-day.
