Marc S. Malkin of New York magazine reports on a recent night at John Street Bar in the Financial District, Gregg Allman, the grizzled seventies sex symbol, was seen approaching a table where Christina Aguilera — sporting pink hot pants, knee-high boots, and fishnets — was cavorting with six female friends. “They all looked horrified,” says one onlooker. “I mean, here was [Allman] with his shoulder-length scraggly hair, cowboy hat and vest, and wraparound sunglasses, and they had no idea who he was.” The D.J. then promptly put on Allman’s 1986 song ‘I’m No Angel’ fortunately, where Gregg pointed to the speakers and explained who he was. “You could tell they were all trying to be polite,” the spy said. “But pretty soon they ran out of stuff to say.” Allman’s rep insists it must have been a case of mistaken identity.
