Mayweather and Pacquiao top Forbes list after money-spinning boutIBTimes UK

He has a penchant for flaunting his immense wealth on social media - even sharing images with wads of cash. But when you have as much money as Floyd Mayweather, justifying your flamboyant lifestyle may not be on your list of priorities. The boxing champ, who is said to be worth $400 - $650m (£272- £443m) has hit out at 'haters' on social media, who he claims are jealous of his success.

Alongside a screenshot of a Google page detailing his net worth, the undefeated pugilist wrote: "It used to be the truth shall set you free. Now it's the truth will make you hate. They're mad because I surpass the ones that they thought were great."

In 2015, Mayweather topped Forbes' annual list of the world's highest-paid athletes. Following his epic clash with Manny Pacquiao, he made $300m: salary/winnings of $285m and $15m from endorsement deals. The impressive feat saw him leading the likes of Ronaldo, Messi, LeBron James and Tiger Woods for the third time in four years.

Although it is not known what prompted his online outburst, days earlier, he was busy splashing the cash as he celebrated his daughter's birthday. Mayweather is believed to have spent over $1m on Iyanna's epic sweet 16 party.

The extravaganza took place in the Grand Ballroom at the Mirage in Las Vegas and featured performances from hip hop heavyweights Drake and Future. He won extra brownie points by gettig pal Justin Bieber to send her a video message and gifted the teenager a 2016 Mercedes G-Wagon. Ahead of her big day the father-of-four shared a throwback of his oldest child in his arms with the simple caption: "HAPPY BIRTHDAY @moneyyaya"

He has proved once again why his fans don't call him "Money" Mayweather for nothing.
