Leonardo DiCaprio, who seems to go out all the time, has a knack for slipping in and out of parties without getting photographed. Now it's clear one way he does it. According to a source, at a recent soiree in New York a photographer for agency Patrick McMullan who had been approved to roam the event, snapped a shot of the actor. DiCaprio confronted him, demanded he delete the shots and, after the photog assented, stood there and watched as he did it.
