Jake Paul will drop a 'diss track' on UFC president Dana White tomorrow in his latest effort to get under the MMA supremo's skin.
Paul taken White to task over fighter pay issues in his promotion, and yesterday confirmed he had bought stock in their parent company Endeavor.
And he will return to his YouTube roots by dropping a music video where he will mock White through rap, as he used to in his social media heyday.
Paul famously feuded with his own brother Logan during the peak of their YouTube rise, where the pair went back-and-forth writing songs about one another which garnered hundreds of millions of views.
And during today's episode of First Take with Stephen A Smith on ESPN, Paul said that he will be releasing another song, this time towards UFC boss White.
"It's really about the fighters," Paul said of his rivalry with White. "I've been in the gym and I've seen how hard these guys work and how mistreated they are and how underpaid all of them are.
"So, it's really about fighter pay and getting them health care, and poking the bear and disrupting his whole entire business.
"I'm dropping a diss track on Dana White tomorrow morning, so you will see that, and I'm not stopping any time soon.
Both Jake and Logan Paul's most viewed videos on YouTube are diss tracks, with the younger brother's iconic 'It's Everyday Bro' going platinum in the United States with over 350million streams.
The song was a shot at Paul's ex-girlfriend Alissa Violet, and also saw him take aim at fellow social media personalities such as PewDiePie and the stars of Magcon and DigiTour.
It remains one of the most disliked videos on the platform, and has been called one of the worst songs ever written by critics of the Paul brothers.
Logan Paul's top viewed video has 278m views and is a diss track at his younger brother; one of three that feature in his top five most viewed of all time.

They have both attempted to forge music careers, but it's been almost two years since Jake has released any songs, and last year said that he would be focusing on fighting instead of putting out new tracks.
Asked when he would drop new music, Paul responded back in October: "Probably never.
"I want to do music, but again it's like 'ain't nobody got time for that'."
He is currently taking a break from fighting to work on promoting the biggest women's boxing fight in history between Katie Taylor and his fighter Amanda Serrano.
Both Paul and Eddie Hearn are working to co-promote the event, which was today confirmed to take place on April 30 at Madison Square Garden in New York City.
He will likely return to the ring this summer, teasing bouts with Tommy Fury and former world middleweight champion Julio Cesar Chavez Jr.
