It was fun while it lasted.
After two tumultuous years together, "Jersey Shore" couple Ronnie Ortiz-Magro and Sammi Giancola have called it quits.
"We are not together," Ortiz-Magro confirmed to Us Weekly at Tuesday's "Paranormal Activity 3" superfan screening in New York.
Following an explosive spat seen on the show's third season in fall 2010 -- he stomped on her glasses and called her a "spoiled bitch," leading to a breakup -- the pair reconciled to film their fourth season in Florence, Italy.
"Being in Italy, in such a romantic atmosphere, brought us together," Ortiz-Magro told Us prior to the show's August premiere. "The first week was rough -- everyone was like 'Oh, my God.' But [Sammi and I] didn't fight at all in Italy. [It was] probably the highest point in our relationship."
Paul "Pauly D" Del Vecchio, who saw the couple fight, break up and make up during the show's filming in Florence, Miami and Seaside Heights, N.J., tells Us he prefers his pal single.
"I love single Ronnie," Del Vecchio says. "When he's doing the relationship thing, I let him do his thing, I don't get involved. When he's with Sammi, he's a different person. She's a difficult woman!"
