Unbeaten US boxing champion Floyd Mayweather, who is undoubtedly the world's best-paid athlete, loves to brag about his wealth on Instagram, as he posted pictures of himself flaunting his fleet of sports cars and a private jet.

The boxer, who topped Forbes' list for the Highest Paid Athletes with 124 million dollars last year, can't help but show off his wealth on the picture-sharing social networking website.

Mayweather's collection includes two different Bugatti Veyrons, a Bugatti Veyron Grand Sport, two Ferrari 458 Spiders, a Lamborghini Aventador, a Porsche 911 Turbo S and a Ferrari 599 GTB Fiorano, News.com.au reported.

Filipino boxer and politician Manny Pacquiao, who has been trying to arrange a bout with Mayweather for years, is unimpressed by his rival's obscene wealth. He said that Mayweather brags about his lifestyle and everything, but added that he doesn't care.

Pacquiao exclaimed that he is just waiting there for Mayweather to sign the contract for a fight.

Among his Instagram posts Mayweather has included his massive shoe collection, boarding private planes and surrounded by money, the report added.
