'Jersey Shore' Gets A New Cast Member In Michael Cera

"Jersey Shore" has quickly elevated itself from simple reality entertainment to full-blown cultural phenomenon. They've been parodied on "Saturday Night Live," poked fun at themselves via a Funny or Die clip and attracted the largest crowd in history to the MTV Newsroom. Now they're getting the chance to welcome a new star into their midst. Actor Michael Cera — the star of "Superbad," "Arrested Development" and the opening-this-Friday "Youth in Revolt" — sat down with some of the stars of "Jersey Shore" to get a full-scale summer share makeover for a series of promos that will run this Thursday (January 7) while a new episode of "Jersey Shore" airs.

Check out these exclusive behind-the-scenes photos, which feature the amiable and awkward Cera getting a full DJ Pauly D hairstyle and a handful of grooming tips from J-WOWW. And for a full look at Cera's interactions with Snooki, the Situation and the rest of the crew, be sure to check out this week's brand new episode of "Jersey Shore."
