A furious Vinny "Sea Biscuit" Guadagnino stormed out of the Jersey Shore crew's current house, jumped into a cab, and headed home—for good, reports TMZ. The big breakup occurred after Vinny had a major fight with another cast mate, sources say. He's holed up in his Staten Island home and feeling "burned out," said a pal. Vinny has been such a pain lately that no one cares to expend the effort to entice him back, sources add. MTV is rumored to be hunting for a new Jersey Shore cast for Season 6 to inject some variety into the relentless party reality show. (More Vinny Gaudagnino stories.)
