There's no need to explain why the world knows Floyd Mayweather as 'Money'.
He's crafted a persona out of an unbeaten record and unparalleled total career earnings, but just what does he spend his millions on?
Property, it seems.
Less than two months after walking away with an estimated $100 million from his fight against 'Notorious' Conor McGregor, Mayweather dropped $25.5 million on a mansion in the exclusive Beverley Hills area of Los Angeles.
The mansion, built in 1992, has its own cocktail bar, gym, and 20-seat personal movie theatre.
On top of this, the residence, described as 'French Style', has 6 bedrooms, 8 bathrooms, and mirrored wall fireplaces, not to mention an outdoor swimming pool, pool house, staff suite for his servants, and a four-car parking garage.
The mansion is right next door to the super-chic Beverly hills Hotel.
If it sounds lush, that's because it is.
Mayweather's new home was the most expensive property-sale in all of Los Angeles County in the month of September, with the undefeated boxer edging out Ted Sarandos, the chief content officer at Netflix, who bought a much smaller property by the beach for a paltry $20 million.
Furniture for the modern mansion cost Mayweather an estimated additional $500,000, and the best-paid sports star in the world dropped all of it - that's $26 million - in cash.
Assuming that cash came in $100 bills, that's around 260 kilos of cash, or, in boxing terms, two Anthony Joshua's.
It's not clear if he moved the money in a van or several dozen schoolbags.
Unbeaten Mayweather might have to get used to toting obscene amounts of cash around with him.
It's been confirmed that the American previously requested he be given until after his August 26 bout with McGregor to settle a tax bill from all the way in 2015, though, it is not known how many millions he owed the United States' Inland Revenue Service.
With a penchant for this type of luxury, it's easy to see how he got himself into that debt in the first place, and why he made the dubious decision to come out of retirment to fight a man with zero professional boxing bouts.
