Floyd "Money" Mayweather

Wanna know the richest athlete in the world today? He's a boxer and his name is Floyd "Money" Mayweather, and the money nickname is there for a reason. His total winnings from boxing this year were a whopping $285 million, almost twice as much as the next athlete on the list, Manny Pacquiao, who is also a boxer. He also earned a total of $15 million from endorsements. He took in at least $220 million just from his fight against Pacquiao this year. You could say that Floyd enjoys spending his money just about as much as he does making it. He has his share of luxury cars and even once had around $7 million in jewelry alone stolen from his house.

His 20,000+ square feet home, or should I say mansion, in Las Vegas is incredible. The picture to the left is just a glimpse of the house, which is valued at about $9 million. This home includes a pool and a hot tub. Not only does it also have 5 bedrooms and 7 bathrooms, it also has a gated golf course with it as well. Floyd's closet may be twice the size of most people's master bedrooms. If you'd like to get a short inside look of the home, check out this video here. In the video he's wearing a $100,000 watch and shows off more than $15 million in cars as well. Or you can check out his Instagram account for this mansion at @bigboymansion

The guy practically sleeps in his money.  There have been some ridiculous ways that he has decided to spend his money throughout his career.  He's bet $1 million on the Patriots before, but that's nothing compared to the $5.9 million he put down on the Miami Heat in 2013. He uses a Cadillac golf cart that is estimated at around $20,000. Jackie Starr, his full time barber, has a salary of over six figures. I repeat, she gets paid six figures just to cut his hair alone. There's countless other ways that Floyd has spent his money in ridiculous ways as well.
