Sammi ‘Sweetheart’ Giancola made a shocking return to Jersey Shore: Family Vacation after an 11-year hiatus, surprising her roommates in a teaser shown at the end of the season six finale. The original cast member of the widely popular MTV show Jersey Shore, Sammi announced in 2018 that she would not be returning for its reboot. Her return also saw the comeback of Ronnie Ortiz-Magro, who previously had a rocky relationship with Sammi while they starred on Jersey Shore from 2009 to 2012. Sammi appeared to be a new catalyst for drama as she confronted the roommates and was shown in a teaser causing some tears to flow. The reunion will return next week with the first part of a two-part reunion.
