Floyd Mayweather Jr, 50 Cent, Marcos Maidana, Manny Pacquiao, Nelly & Shantel Jackson: Celebrity Feud

Floyd Mayweather is training for his upcoming fight against Marcos Maidana, but it seems everyone else wants to take a shot at him about his apparent lack of intelligence. "Money" Mayweather has had a celebrity feud with 50 Cent, Nelly and Shantel Jackson, but now it seems like Manny Pacquiao wants to get involved. Why, you ask? The pair have never got along, and there are rumours of a 2015 bout between the two. During a time where many things are becoming a long-lasting trend, it seems bashing Floyd has become one for some of the most famous stars in the world.

Fiddy was once best friends with Floyd, but lately he's taken to social media to repeatedly insult Mayweather. First, he laughed about how Nelly had stole his ex-partner, Shantel, then he uploaded a video of himself challenging Floyd to read a page of a Harry Potter book, suggesting he couldn't read in the process. That quickly made people question the boxer's intelligence, and Mayweather hasn't had much of a response.

Pacquiao recently joined in, saying, "I think I finally understand him ... what he says ... how he acts ... and I don't like it. But what l learned and heard from him, well, I realize why he is like that. I understand sometimes when the people are not educated they just talk to talk. He sets a very bad example."

Floyd tends to stay focused, but one wonders, will he hit back after his upcoming fight with Maidana? If he runs in to one of these celebrities, you can bet he'll try and get confrontational.
