Fans of the MTV reality series Jersey Shore cannot wait for E!'s Reunion Road Trip: Return to the Jersey Shore on Sunday — which comes fresh off the heels of Jennifer "JWOWW" Farley, Nicole "Snooki" Polizzi, Sammi "Sweetheart" Giancola, Deena Cortese, Mike "The Situation" Sorrentino, Pauly "DJ Pauly D" DelVecchio, and Vinny Guadagnino reuniting for a Burger King commercial. It's been noticed that cast member Ronnie Magro — who is also part of Famously Single — has not been present for any of the festivities.

This has nearly everyone asking the question: What happened to Ronnie from Jersey Shore? His rep confirmed to TooFab that there is a reason Sammi's ex-boyfriend hasn't been with his former co-stars — and it actually doesn't have anything to do with her.

When it came to the Burger King commercial, his rep explained to the publication that "[it] was shot on the East Coast, but he is in a holding position right now because he's filming on the West Coast. If there was an opportunity for a reunion he would be excited and would love to be with his fellow castmates."

Former couple Ronnie and Sammi.

"Ronnie was busy shooting Famously Single, which I kind of knew about that. Deena couldn't make it because she was working or doing something, and Vinny was busy — it was kind of a last-minute thing though, like, 'Hey, do you guys want to get together and go down to the Boardwalk?' Like yes, I'm there!" she quipped.

Ronnie joined his other ex-girlfriend Malika Haqq, Dorothy Wang, Chad Johnson, Karina Smirnoff, Tiffany "New York" Pollard, and David McIntosh for Season 2 of Famously Single where Hollywood's most ~single~ stars work on their dating and relationship habits. He briefly moved on with the Kardashian BFF, who recently revealed he was "aggressive") during their time together.

His relationship with Sammi was a major storyline for Jersey Shore, as fans remember watching them get together and fall apart too many times to count. Today the two don't even follow each other on Instagram, and considering Sammi has a new man in her life, we think it's safe to say that relationship is permanently over.

JWOWW exclusively told In Touch that "they both moved on" and she didn't think they would reignite their old flame, though Sammi revealed that she does wish him well.
