Breaking news! We are hearing unconfirmed reports that normally even-keeled Jersey Shorer Vinnie Guadagnino has angrily stormed out of the Seaside Heights home where the cast just began filming their fifth season.

An "insider" said that Guadagnino had "had enough" of the constant inter-cast fighting at the house, and left in a huff. "He's getting the rest of his stuff and leaving again," the source said. "His mic pack is off and he's trying to force them to give him back his phone to go home." An MTV spokesman declined to comment, though we have a sneaking suspicion that Guadagnino will be back.
