50 Cent and Floyd Mayweather, who were once good friends, have been in an ongoing feud that’s now centering around the ALS Ice Bucket Challenge.

50 Cent Floyd Mayweather Feud

After getting nominated, 50 Cent decided to call out his ex-pal Mayweather. However, instead of following suit with the bucket of ice, 50 Cent offered to donate $750,000 to charity if Mayweather could read one page of a Harry Potter book in public without messing up.

Later in the day, 50 Cent changed up the challenge, telling Mayweather that Jimmy Kimmel would have him on his show and that he’d only have to read a passage from Dr. Seuss's Cat in the Hat.

"Got a phone call from my man, Jimmy Kimmel," 50 Cent said. "Jimmy said that if Floyd accepts the challenge, he'd put it on the actual show. You can read it on the show. We don't want to put pressure on you, we know you can't pronounce those words in that Harry Potter book. So we're going to let you read Cat in the Hat."

In response to the challenge, Mayweather decided to post pictures of two recent paychecks for his fights, which have a combined total of over $72 million.

50 Cent was not impressed with the checks. He also mocked the fighter for working for Oscar De La Hoya’s Golden Boy Promotions.

“I guess you want people to see your math is better then your reading,” 50 Cent captioned the video. “Get a account Floyd, the people around you are using you. if you mad at me call me or come see me.”
