Over the course of their eight-year relationship, Ronnie Ortiz-Magro and Sammi "Sweetheart" Giancola practically had more breakups and make-ups than Jersey Shore had episodes, and he was usually the one to blame. He made out with random girls in random nightclubs in Season 2, for example, but he also reportedly cheated on Sammi with a fellow reality star: Bad Girls Club star Morgan Osman.

We first heard about this alleged affair when Tough Love star Arian Mayer put Ronnie on blast in September 2011, tweeting, "So @MTVsammi I thought you should know that @mtvronnie was f–king my girl @Morganbritt724 last weekend and now they are at Wet. Sorry."

Arian elaborated on the situation in a statement to TheDirty.com (per Starcasm): "So the dumbass f–ked my friend a week ago, and she is here in Vegas visiting me. I never hooked up with Ronnie, he hooked up with my friend. I dropped her off at Wet Republic to hang out with Ronnie while I ran some errands. I came back to meet up with her and a few friends I went to college with, and Ronnie wouldn't let me in their table because he said I was 'bad for his Image.' So I blew that ugly m–get's spot up. P.S. They gave Ronnie a table behind the DJ booth. He is so lame he doesn't even get a cabana or a bungalow." (Ronnie didn't take the allegations lying down, calling Arian a "hooker" and saying "her fish was old for [his] market.")

Anyway, it's all over now. In a 2017 episode of Reunion Road Trip Mike "The Situation" Sorrentino asked Sammi about the status of her relationship with Ronnie. "That door is closed and will remain shut for a long time," she responded.

Meanwhile, in an episode of Famously Single, Ronnie seemingly blamed Sammi for his infidelity. "I don't think that she ever fulfilled me inside," he told his counselor. "I guess that's why I cheated. Maybe she wasn't exactly what I needed."

All's well that ends well, though. Sammi is dating Christian Biscardi, while Ronnie is expecting a baby girl with girlfriend Jen Harley. After such a highly publicized relationship roller coaster, it's probably better these Jersey Shore stars are tracking toward separate happy endings.
