FLOYD MAYWEATHER and Jake Paul were involved in an ugly brawl after the YouTuber stole the boxing legend's CAP.
Former four-weight world champion Mayweather will in an exhibition bout at Miami's Hard Rock Stadium on June 6.
The pair, 44 and 26 respectively, got their first glimpse of one another on during their first pre-fight press conference.
And there appeared to be no love lost between the duo, who initially exchanged pleasantries as they stared into each other's eyes.
But the chaos came moments later as a scuffle ensued after Logan's younger sibling confronted the former pound-for-pound king.
It all kicked off shortly after Jake shouted 'you wanna make it two in one night' to 'Money' Mayweather.
As he made his way over to confront The Problem Child, a fire-up Mayweather said: "Yes."
Pandemonium ensued after Paul stole Mayweather's hat - with the pair eventually separated after members of their entourages got in between them.
But Mayweather was still clearly irate after the encounter and could be heard shouting: "When I catch you, motherf***er, I'll kill you motherf***er! You crazy?!
"I don't know who the f*** he thinks he's playing with, but I don't play no motherf***ing games!
He recently said: "A lot of times they say, 'Oh, Mayweather, he's doing exhibitions' they be like, 'It's bad for boxing'.
"But at the end of the day, I look at my children, I look at my grandson, I look at my mother, I look at my father.
"My mother's a millionaire, my dad's a millionaire, my children are millionaires, my little grandson's a multi-millionaire and he doesn't even know it."
