Mayweather, 44, will return from boxing retirement on June 6 when he meets no-mark Logan Paul in the ring in Miami, but it was the younger brother who left the undefeated legend of the sport spoiling for a fight.
Cameras on standby at the pre-fight press conference picked up the extraordinary scenes as Mayweather was seen initially giving an interview stating he would happily go up against both brothers on the same night, one after the other.
Jake Paul – who recently knocked-out retired MMA star Ben Askren inside 60-seconds took exception to the comments and decided to daringly step up and call Mayweather out.

The pair then faced off as a tensions rose, with Mayweather shouting into the face of the 24-year-old ‘I am my own boss.’
Paul opted to get one over on the boxing icon by pulling the cap from his head before turning to run away. He could be heard repeatedly taunting ‘got your hat, got your hat,’ sending Mayweather spinning into a rage.
Bedlam soon broke out, with both the Mayweather camp and the opposing camp of the Paul brothers camp coming to blows and being separated by security.
Logan Paul was seen diving in to pull his brother away, after the youngster appeared to be bundled to the floor by part of Mayweather’s entourage.
Mayweather himself was held back by large security guards, further heightening his fury and the chaos continued to erupt.

Unable to get his hat back, Mayweather was seen being ushered away from the scene while shouting: ‘Don’t disrespect me like that, you don’t know who you’re f*****g playing with!
‘I’m gonna kill that motherf*****, when I catch you. Are you crazy? You don’t know who you’re f*****g playing with.’
Footage from the scene concluded with Jake Paul being hauled away into a side room, with his t-shirt visibly stretched at the collar from the confrontation.
Later, the YouTuber star uploaded a video to his personal Instagram account in which he continued to attempt to goad Mayweather about his hat, though boxing fans were quick to point out the welting and bruising of what appeared to be a rapidly emerging black eye.

Jake Paul now has three professional boxing fights to his record with three victories, after defeating fellow YouTuber AnEsonGib and former NBA star Nate Robinson before beating Askren.
His brother Logan Paul, who will step inside the ring with Mayweather in just over four weeks, has one professional fight to his name against fellow YouTuber KSI, which he lost.
Earlier, before the commotion, Mayweather had been posing for pictures on stage and insisted to him it was not a ‘fight’, while promising fans he would serve up a guaranteed knockout.
Mayweather said: ‘I’m 100 per cent sure it’s going to be a knockout.
‘It’s not really a fight for me. It is to him. For me, it’s just going out and doing what I do. This is all about entertainment. This is the biggest event since Covid hit.’

Mayweather has returned from boxing retirement on several occasions to take part in lucrative exhibition events.
In August 2017 Mayweather shattered box-office records when he fought UFC star Conor McGregor in the boxing ring, taking victory via a 10th round TKO.
The American star last fought on New Year’s Eve 2018, when he knocked out Japanese kickboxer Tenshin Nasukawa in a crossover event.
In what was a huge mismatch, Mayweather put the Japanese star down three times in less than two minutes before the towel was thrown in.
The boxing icon was reported to have banked $9 million (£6.5m) for his participation and victory.
