50 Cent challenged Floyd Mayweather to read a page of Harry Potter on Instagram in lieu of the ALS Ice Bucket Challenge as he accused him of inability to read, but Power 105.1's Charlamagne released an audio wherein Mayweather is struggling to read a scripted radio spot - which added fuel to the fire.

The Floyd Mayweather and 50 Cent grouse to each other was once again heated up, when 50 Cent challenged the undefeated American boxer to read a page of Harry Potter, which was later downgraded to reading The Cat in the Hat on Jimmy Kimmel Live.

Mayweather stayed silent about the whole issue then, an audio of himself recording a radio bumper recently emerged. The audio was a simple script identifying a charity and himself and it is pretty obvious that the boxer is having a hard time.

"I'm Floyd Mayweather, and I've joined IHeartRadio for the Show Your Stripes movement to support the hiring of vets. Go to ShowYourStripes.org, a website that connects veterans with employees and helps businesses find candidates with the best training," the man in the audio said.

Mayweather's publicist Kelly Swanson defended the boxer and said on an email to Media Members that the reports about Mayweather's inability to read, which was all over the Internet are not true.

Swanson provided a couple of videos of Mayweather reading lines for promotions for his fight against Marcos Maidana and CBS sports.

Meanwhile, Charlamagne Tha God feels bad about releasing the Floyd video as he didn't realise adult illiteracy was quite so prevalent.

"In hindsight, I feel a little bad about it, just a little, because I didn't know there were that many people out there suffering from illiteracy," Charlamagne said according to a report on Bossip.com.

Thus far, Floyd Mayweather's only response to his illiteracy has come from his check book. He posted a photo on Twitter and Instagram with the caption, "Read this $72,276,000.00. God bless."
