MTV Jersey Shore's Ronnie Magro and Sammi Giancola are officially back on and back to the old ways of their famously tumultuous relationship. The reality show couple fell into each other's arms the moment the show began shooting the second season but quickly hit some road bumps and RadarOnline.com has the exclusive details of their rocky season two romance!

Despite a romantic beginning, the couple had a blowout fight at a club recently, which ended with Sammi storming out in anger. "Sammi got into a fight with Ronnie and she left the club early and he was later seen dancing with a blond girl who was a waitress there," a source said about their recent outing to the Miami hot spot Klutch.
