First to jump in on the beef between Soulja Boy and Chris Brown was Floyd Mayweather in support of Soulja. Then 50 Cent elected to stand up for Chris Brown and called Mike Tyson to ensure that Brown defeats Soulja Boy. Then Mike Tyson dropped a diss track, and now, RiFF RaFF says he wants to fight 50 Cent.

Well, the Pink Panther says that he would step into the ring with 50 Cent for $2 million in two Instagram posts. The two posts, a video and a photo feature RiFF in the gym getting some sparring in and a quick flex for the mirror. Both posts have captions that would lead one to believe that the rapper is serious.

It appears that 50 Cent hasn't responded to the challenge yet, but it's really only a matter of time. Who you got your money on?
