Floyd Mayweather Jr. and 50 Cent have had a public feud going all summer via social media. After a NYC radio show aired a clip of Floyd Mayweather Jr. struggling to read a drop, 50 cent issued a reading challenge to the undefeated boxer. If Floyd could read an entire page of a Harry Potter book, 50 Cent would donate $750,000 to charity. At first, Mayweather replied by flaunting his success. But now, Mayweather has stooped to a new low by involving Fifty's son in their beef.
