The 39-year-old, who reportedly made more than £160million for his fight against Manny Pacquiao in May 2015, is more famous for his fleet of cars - but has broadened his horizons since retiring.
The boxing legend used his planes to embark on a world tour after his final fight against Andre Berto, as well as putting on a tour of Europe where thousands of fans flocked to his shows to meet him.
Mayweather's latest venture is his plan to open a strip club called Girl Collection in Las Vegas, having built a reputation of spending tens of thousands of dollars in such establishments
The former boxer, who is believed to have a net worth of close to £500m, announced the move on his Twitter account on Sunday.
Talk of Mayweather returning to the ring has died down since UFC star Conor McGregor was booked for an Octagon bout in August, leaving 'Money' without a verbal sparring partner to garner interest.
However, less than two weeks ago Mayweather told the Los Angeles Times he could yet be tempted to lace up the gloves again.
'For the right price, I may come back,' said the five-division world champion.
'A lot of fighters have to box. I don't have to box. I don't get the urge to go to the boxing gym. My urge is giving back to the sport now, helping [promote] the young fighters.
'People have to realise, when I look at my Uncle Roger [his former trainer, riddled with health issues] and even Ali, boxing is wear and tear.'
