Undefeated American fighter Floyd Mayweather Jr. seems to be staying true to the adage "If you've got it, flaunt it." Recently, Mayweather made another ostentatious show of his luxurious lifestyle when he shared a picture of him with his private jet and expensive car collection in a new Instagram post.

"Welcome to my toy world," Mayweather captioned the photo flaunting his Bugatti Veyron, Bugatti Grand Sport, Ferrari 458 Spider, Lamborghini Aventador, Porsche 911 Turbo S, Ferrari 599 GTB Fiorano, and private jet. "Who wants to come out and play?"

According to TMZ Sports, Mayweather's fleet of luxury cars cost as much as $7.3 million. His Bugatti Grand Sport alone costs $2 million.

It wouldn't be the first time that the Grand Rapids native has bragged about his wealth on social media. He has taken to Instagram to flaunt the expensive purchases he makes with his hard-earned money.

In October 2014, Huffington Post and Business Insider has compiled those times that Mayweather has bragged about his luxury lifestyle on Instagram. On the popular social media photo-sharing application, Mayweather is often photographed showing off bundles of dollars, expensive luxury watch collection, winning bet slips, purse checks, shoe collection, and pricey pieces of jewelries.

Having claimed the top spot in Forbes' annual list of highest-paid athletes, Mayweather doesn't mind spending a lot of money on luxury things that are certainly worth the cost. He has reportedly earned $400 million after turning professional in 1996. In Mayweather's last nine bouts, he has earned at least $25 million for each. Mayweather's biggest payday came when he fought Canelo Alvarez in September 2013. The said bout billed as "The One" generated a total revenue worth approximately $200 million, which included pay-per-view buys, merchandise, closed-circuit, and gate pass.

In 2014, his gross earnings amounted to $105 million. He is the first athlete in addition to Tiger Woods to have hit the $100 million earnings threshold. Mayweather may not have exclusive lucrative contracts with big companies, but his career earnings are more than enough to beat Cristiano Ronaldo, LeBron James, and Tiger Woods to claim the number one spot.
