Floyd Mayweather Jr partied in Las Vegas at the 26th birthday celebrations of American popstar Chris Brown on Tuesday.
The pound-for-pound boxer was spotted partying for the first time since beating Manny Pacquiao on points at the MGM Grand Garden Arena last Saturday.
The 38-year-old is believed to have earned upwards of £130m for the fight, and it appears that he spent some of that cash on a night out at luxury club Drai's.
Brown selected the club to host his birthday, which falls on Cinco de Mayo, and Mayweather was spotted with a large entourage, who enjoyed unlimited glasses of champagne, according to the Daily Mail.
Meanwhile, Mayweather is reportedly being sued for £13m by his ex-girlfriend Josie Harris, who is the mother to three of his children.
