Jake Paul has mentioned Dee Devlin in a diss track aimed at UFC owner Dana White this Friday.
The Youtuber turned undefeated pro boxer released a song aimed at the UFC today as he puts pressure on the company to pay fighters more.
But the American couldn't help but throw some shade at UFC star Conor McGregor, while mentioning his fiance.
Paul says in the song: "McGregor I ain't see you win in five years, you rich little weirdo, ugly ass veneers. Took so many losses wound up at VMAs, tryna fight with MGK, no surprise here.
"Lamborghini boat but your career is sinking, really got me wondering what Dee is thinkin'."
This is just a few seconds of the track on Youtube which lasts more than three minutes - The track begins: "Now everybody from the UFC, put your motherf****** hands up and follow me..."
White is the first to be targeted as the chorus chants: "F*** Dana, f*** Dana White, F*** Dana, f*** Dana White, F*** Dana, f*** Dana White..."
Paul then turns his attention to UFC welterweight contender Jorge Masvidal with whom Paul was previously friends but who has now been offered $5million to fight the social media star.
"First of all Masvidal, you ain't rich, 50 fights for $5m that ain't s***," Paul says before addressing the issue of fighter pay.
Paul finishes his tape by returning to White, insisting he will not let up in his fight to improve pay for the promotion's stars.
He also refers to a challenge he and White had whereby Paul would submit to a drug test while White would be tested for cocaine use.
"Dana, pay your fighters more, give them healthcare you scumbag," he concludes. "I haven't met a single person who says anything good about you.
"I passed my drug test and you went silent. I'm keeping my foot on your neck until you tap b****.
"Stop raising your pay-per-view prices on fans and not paying fighters more... greedy, old, lonely, bald b*****."
