The undefeated champion who has never lost any of his professional bouts showed off 25 stacks of $100 dollar bills on board his private jet as he prepares for his mega-fight with Conor McGregor next month.



In 2015, the American boxer earned $100million from his record-breaking fight with Manny Pacquiao.

Posting the dollar bills on Instagram, Mayweather went ahead to proclaim on his upcoming fight saying: 'Champion Predictions: I'm gonna make a $**t t$n of money on August 26th.'
