50 CENT IGNITES NEAR-RIOT:" 50 CENT re-ignited a bevy of hip-hop beefs during Hot 97's Summer Jam at Giants Stadium on Saturday. First, the bullet-riddled rapper enraged Hot 97 program director Tracy Cloherty by airing a video on stage that ridiculed the likes of Lil' Kim, Ja Rule, Ashanti and Joe Budden. After Cloherty yanked the video before it ended, 50 spotted former friend Bang 'Em Smurf, who was seated in the front row, and threw a wad of cash in his face in response to Smurf's claim that 50 owes him $150,000. Police in riot gear broke up the resulting scrum between 50 Cent's posse, G-Unit and Smurf's crew, the Silverback Guerrillaz. When he finally performed, 50 dissed headliner R. Kelly by changing the words to Kelly's song, "I don't see nothing wrong with a little bump and grind" to, "I don't see nothing wrong with urinating on little girls" — a reference to the R&B lothario's current legal woes."
