Sammi “Sweetheart" Giancola is making her debut on Jersey Shore: Family Vacation, but it's not the best idea for her to film with her ex, Ronnie Ortiz Magro. When the spinoff was first announced in 2018, all of the original roommates were set to be in the spinoff series except for Sammi. At the time, she had opted out of the opportunity to reunite with her former roommates in an effort to avoid her toxic ex-boyfriend and costar Ronnie. While he did in fact return for the new show, Ronnie hasn't filmed with the cast in nearly two years.
