Just how sexy is Robert Pattinson's new Dior ad campaign? It's already been described as "sexually explicit," and now a new report has come out to say just how far the advertising goes.

Life & Style spoke to a source close to Dior who describes that "in one scene, Rob's shirtless while simulating a foursome with three hot blond models." Apparently the sequence is so racy that Pattinson's on-again girlfriend Kristen Stewart "will be livid."

This expands on a report already released about the ads. That story's insider said Dior "is pushing the boundaries of what you can get away with in advertising." The TV commercial and billboards are expected to be released in either May or June, and the foursome isn't the other steamy ad fans have in story.

In another, "Rob and the model are in a swimming pool making out and he's seen giving her a blow back with a cigarette at one stage, too," the L&S source says. "Kristen has no idea what she's in for."
