They may be reunited and on better terms these days, but Ronnie Ortiz-Magro and Sammi Giancola's volatile relationship sure took a toll on their roommates while shooting the show's Italy-set episodes this spring.
In a new preview from Thursday's show, Vinny Guadagnino takes Giancola to task for her erratic behavior around her then ex-boyfriend Ortiz-Magro during a drunken night out.
"I'm done with him and you being drunk," Guadagnino tells her. "When Ronnie and Sammi are drunk, they turn into different people and there's no getting through to them," he later reasons in the clip.
Giancola's fed-up roommates Deena Nicole Cortese and Jenni "JWoww" Farley also side with Guadagnino. "This needs to stop! You're not in high school and you need to grow up and find a happy medium," Farley snaps of the exes' immature spats.
But as the exclusive preview shows, rather than take her roommates' concerns to heart, Giancola gets defensive.
"I have feelings for Ron and I always will," she angrily tells the group. "It's hard living with your ex-boyfriend and going out. I'm dealing with it the best I can, and I feel like I've been doing pretty f--king good!"
Her efforts must have worked: Ortiz-Magro tells the new issue of Us Weekly that he and Giancola rekindled their romance overseas.
"Being in Italy, in such a romantic atmosphere, brought us together," Ortiz-Magro says, noting that the featured fight with their roommates in the above clip was one of many. "The first week was rough -- everyone was like 'Oh, my God.' But [Sammi and I] didn't fight at all in Italy. This is probably the highest point in our relationship."
