Diddy Mediates Rick Ross and Floyd Mayweather, Jr. Altercation

This past weekend things almost turned ugly between world champion boxer Floyd Mayweather Jr. and rapper Rick Ross. Rumors of beef between Mayweather and Ross began earlier this year after photos of Ross' ex-girlfriend and kids with Floyd and 50 Cent were leaked to the Internet.

50 Cent and Mayweather's well-documented friendship has only fueled further tension with Ross. At last weekend's grand opening of Vanity nightclub at the Hard Rock Hotel in Las Vegas, the two men and accompanying entourages literally bumped heads in the hotel lobby. The party which was being hosted by hip-hop mogul Sean "Diddy" Combs almost came to a halt when tempers flared and words started being exchanged between the two crews.

However before any physical altercation ensued, Diddy came to the rescue and deflated any possibilities of violence from occurring. Diddy reportedly acted both as a mediator and peacemaker and stepped in between the two. Both parties eventually returned to the event with no further incidents. Diddy's camp and Ross's camp both declined to comment on the situation, but Floyd's father Mayweather Sr. confirmed to TMZ that there's been a real beef between Floyd and Ross for some time now because Ross has allegedly been, "talking s---."
