Tensions are rising between former friends, boxing sensation Floyd Mayweather and rapper/fight promoter 50 Cent.

Legendary rapper Curtis Jackson, better known as 50 Cent, recently discussed his now defunct relationship with all-time great Floyd Mayweather.

Last month, iconic rapper 50 Cent launched his new energy drink company named "Street King," and collaborated with boxing legends Mike Tyson and Floyd Mayweather to shoot a commercial for the drink that, ironically, parodies the popular movie 'The Hangover.'
