No, this is NOT a throwback picture!
Vinny Guadagnino posted an Instagram snap with his former costars Ronnie Ortiz-Magro and Sammi "Sweetheart" Giancola — making it a mini-Jersey Shore reunion.
“Rahnn Stahppp[sic],” Vinny captioned a picture of the group, referencing Sammi’s pronunciation of her (ex?) boyfriend's name.
The three reality stars gathered to celebrate Sammi’s 29th birthday, but there's been speculation that the on-again, off-again couple may be dating again.
Though the two broke up “permanently” in 2014, it seems they just couldn’t stay away from one another!
Well — we guess this is why you shouldn't ~fall in love at the Jersey Shore~!
