The pound-for-pound king uploaded a picture of cases of his cash while
flying on his private jet having watched LA Lakers lose to San Antonio
Spurs in the NBA.
He has recently returned from a tour to the UK where he spoke to fans across a range of cities across the country.
Fans paid up to £2,000 to meet their hero during the two-week trip.
Mayweather, aptly nicknamed 'Money', earned £200million last year
alone, largely down to the 'fight of the century' against Manny
Pacquiao.
He came out on top against his Filipino rival, before winning his 49th and final fight against Andre Berto in September.
Despite being just one win away from a half century, he insists his career in the ring is finished.
