Floyd Mayweather Jr, 50 Cent, Justin Bieber, Marcos Maidana, Amir Khan, Nelly, & Shantel Jackson: 'Nellyville': Nelly Discusses Birthday, Feud As Bieber Prepares For Knockout

Floyd Mayweather has hit out, saying that Justin Bieber is "boxing ready" and one can wonder, is he coming to knock Nelly and 50 Cent out for Money Mayweather? Floyd is preparing to possibly fight Amir Khan, but he's been busy feuding, largely over his ex-girlfriend, Shantel Jackson. Despite beating Marcos Maidana, people are still questioning the world champion, but he and Bieber are looking to prove the world wrong. If they run in to one another, one can wonder, would Bieber be the first to throw the knockout punch if Fiddy or Nelly got abusive?

Bieber has been toying around with his boxing training for a long while, but in recent months, it's seemed like he may genuinely look to make the switch from music star to boxer. Floyd recently praised Bieber, and he held nothing back, suggesting that he could easily go on to become a star in the sport if he chooses to. The question is, does Bieber want to box?

Floyd has had beef with Nelly, who recently tried to squash the beef, instead focusing on his 40th birthday and his Nellyville show, but one can wonder, would adrenaline run high if these stars all ended up at the same party, or restaurant?

Will Bieber attempt to become a professional boxer, or will he stick to using it as a fitness plan? Mayweather may soon retire, but Bieber's story might just be beginning, and if his career takes off, you can bet that Floyd would have a front-row seat.
