Floyd 'Money' Mayweather is the richest star in the history of boxing, having reportedly become the first fighter to earn over US$1bn in the hardest game.
After 21 years in the paid ranks, the 40-year-old is enjoying retirement following victory in his $NZ646m mega-fight with Conor McGregor last month.
And Mayweather, who grew up amid poverty and drugs in Grand Rapids, Michigan, has been showing off his wine and watch collection in the Beverly Hills mansion he recently bought for NZ$34.9million.
The 40-year-old is normally based in Las Vegas, where he lives in his extraordinary 'Big Boy Mansion'. He also owns a massive property in Miami which cost a reported NZ$10.5million.
Now, in the neighbourhood famous for the glitz and glamour of its A-list residents, Mayweather is enjoying a life of luxury in the 15,096 square-foot, six bedroom house next to the famous Beverly Hills Hotel.
'Money' showed off his extensive glass-faced wine cellar as well as his remarkable array of jewel-encrusted watches.
"Relaxing in 90210," Mayweather wrote alongside a photo of him inside the mansion, that includes a sculptural staircase with an LED-lit banister, a living room with 10 sets floor-to-ceiling French doors and an ebony-panelled library.
Videos posted on the former fighter's Instagram showed Mayweather in a vast room surrounded by a marble fireplace and impressive chandeliers.
After flirting with retirement on a number of occasions in the past, the 40-year-old claimed he will give up the game for good after beating McGregor at the T-Mobile Arena.
