Get ready for a new season of drama at The Jersey Shore: MTV reality stars Ronnie Magro and his onscreen girlfriend Sammi “Sweetheart” Giancola have reportedly called it quits in a bitter split that has left the hard-partying twentysomethings “barely speaking to each other.” The former couple has reportedly cancelled two recent events that they were scheduled to appear at together.

“Ronnie and Sammi aren’t dating anymore, and they don’t want to do any public appearances together because they can’t even stand being in a room together” a source close to the one-time lover told RadarOnline.com this week.
