Justin Bieber, 50 Cent, Shantel Jackson, Floyd Mayweather Jr, Nelly & Orlando Bloom: Celebrity Feud: Entertainment & Sports Stars Training For Possible Fight Rematch? Who Wins Bouts?

Some say that celebrities have too much time on their hands and too much money, and certain celebrities do not do anything to help change that perception. Justin Bieber and Orlando Bloom recently had a scrap, and rumours have persisted that they'd fight one another again, and would train for the bout. Bieber's close friend Floyd Mayweather Jr has had his own troubles with Shantel Jackson, 50 Cent and Nelly. Could Mayweather train Bieber for a possible fight, and how will he deal with his own celebrity feuds? Bieber has been seen doing boxing training, so watch out, Orlando.

Videos of Bieber doing boxing drills has recently emerged, not long after many suggested Mayweather would train him. Could Bieber be training for a rematch with Bloom? The pair had a fight in a crowded restraint, and it's believed their issues are yet to be resolved. The pop sensation put the video on Instagram Thursday, but posted the words "Not a boxer but it's cardio and it's fun so don't judge me lol."

Perhaps Floyd has sent him instructions via email, as he has a fight with Marcos Maidana approaching, possible fights with Shawn Porter, Kell Brook and Amir Khan to follow, and on top of all of that, he has his own celebrity fights to deal with. His ex-partner Jackson is now dating R&B singer Nelly, and the pair are believed to dislike one another. One-time close friend 50 Cent didn't help matters by teasing him via social media.

The Bieber and Mayweather world is a bit crazy right now, but then again, when is it ever calm? Could there be any celebrity fights approaching in 2014, and how can they resolve their differences?
