Jake Paul is doing a pretty good job of winding everybody up in combat sports at the moment and used his brawl with Floyd Mayweather to reignite his row with Conor McGregor.
The YouTube star came to blows with Mayweather on Thursday at the first press conference for his brother's upcoming exhibition bout against the unbeaten boxer.
The pair squared off face to face at the Hard Rock Stadium in Miami, as Paul then nicked the baseball cap off Mayweather's head and shouted: "Gotcha hat."
Mayweather immediately lost his temper as things quickly turned ugly amidst a sea of reporters, with his entourage even getting involved to try and get the hat back.
Seething with rage, Mayweather shouted: "Don't ever disrespect me, I'm gonna f*** you up. I'm gonna kill that motherf*****."
Both fighters were eventually kept apart but the heated exchange rumbled on for several minutes, leaving Paul with a black eye, and UFC star McGregor was not in the slightest bit impressed.
"The kid is curled up, didn't fight back once, and Floyd is still around acting the tough guy. The kid actually just pulled this shambles of a situation Floyd is in out the drain for him," McGregor wrote on Instagram.
"He should thank him. It's embarrassing!
"Pro to pro it's embarrassing. He will not scratch 10m for this fight and he knows it. It was cancelled once already. The world is watching this on Twitter.
"He'd fight a half decent pro and command 20m upwards yet it's this s***."
"Whatever way you spin this it's sad.
"Fight someone for real, on your record, or f*** off mate.
"Slap head."
Paul has repeatedly tried to call out McGregor in the past but with little joy.
The Irishman recently made his feelings clear about the latest craze of celebrity fights, tweeting: "UFC high level fighting > Blogger jacka** boxing."
But Paul couldn't resist using McGregor's latest rant to try and open up old wounds.
Replying to McGregor's post, Paul wrote: "Gotcha hat."
His row with Mayweather started when the boxer was on stage and Paul began untying his rivals shoelaces.
Off stage things turned up a notch as Paul suggested he fight Mayweather on the same night as brother Logan.
"What's up? You looking over here? What's up? You wanna run it two in one night?" Paul said.
"Absolutely!" Mayweather replied, before Paul said, "Lets make it happen."
Mayweather and Logan are due to go head to head on June 6 in a bout the 44-year-old has boasted will net him around $100million (£72m).
