Supermodel Naomi Campbell launched her new fragrance -- named, appropriately, Naomi Campbell -- among friends last night, and things got a trifle bizarre. "Some guy just cut some chick's hair," Sandra Bernhard reported to PEOPLE as the party started heating up at a lounge tucked inside New York's Grand Central Station. "It was very provocative." Bernhard was referring to a tipsy, clipper-toting hairdresser named Christian, who moved beyond his first willing client and continued to try to cut away at the heads of other guests -- until security forcibly removed him. By then the soiree was in full swing. But the party was really all about Naomi. "Every party she's involved in, the most dramatic and most fun part is when she shows up," Russell Simmons told PEOPLE. Among the others who gathered to celebrate included Q-Tip, Miramax honcho Harvey Weinstein, actor Billy Zane, model Stephanie Seymour, designer Marc Jacobs, rapper Ja Rule, Sean "Puffy" Combs and his mother.
