Jake Paul has apparently been left with a black eye and "busted tooth" after stealing Floyd Mayweather's hat.
Despite the fact that it's his brother Logan facing the undefeated boxer next month, Jake, 24, decided to rile Floyd, 44, at the Hard Rock Stadium in Miami by stealing his baseball cap.
He subsequently posted a video of the incident to Instagram yesterday (May 6) that was captioned: "gotcha hat @floydmayweather."
Watch the altercation below:Since the video was posted 12 hours ago ahead of Logan and Floyd's fight next month, it has been viewed over five million times.
The pair can be seen in the clip facing up to each other, before Jake steals Floyd's hat and tries to run, which does not end well for him.
The undefeated boxer immediately grabs the YouTuber after the stunt, but it's not known exactly how much damage he goes on to cause because the incident took place in a crowded room.
The fight was eventually broken up by security, and Jake and Floyd both looked more than a little flustered.
Mayweather can be seen angrily walking away and screaming "I'll kill you motherf**ker".
He shouted: "I'll kill you motherf*****! Are you crazy? I'll f*** you up, motherf*****. I don't play motherf***ing games. I'll f*** you up."
It's not known if Jake set up the whole stunt so that he could say "gotcha hat" on film.
Jake went on to try and sell a range of "gotcha hat" hats on Instagram and could be seen with the beginnings of what looked like a black eye from the incident, the Mirror reports.
Social media commentators then began to speculate about whether or not one of his teeth had been damaged in the altercation.
Reacting to Jake's appearance after the altercation, one Twitter user wrote: "Floyd gave Jake Paul a black eye and fucked up one of his teeth. My day has been made."
A second added: Jake Paul got a black eye from floyd Mayweather. well deserved [sic]."
A third went on to sum up what happened in the aftermath, writing: "pretty sure floyd got his hat back and jake got a busted tooth, black eye and ripped up t-shirt [sic]."
Mayweather described the brothers as "fake fighters" and said that he'd fight the pair on the same night.
Logan replied: "The only thing that's fake on this stage is Floyd's f***ing hairline."
Following high-profile fights with a YouTuber, former NBA professional, and former MMA fighter, Jake is at 3-0.
While Floyd remains an undefeated fighting champion, having won over 50 times, Logan is 0-1 having tried and failed to enter the world of boxing with a fight against YouTuber KSI.
Logan and Floyd are set to have it out on June 6 after their fight was signed off in April.
