Sammi "Sweetheart" Giancola has spurred speculation that she's single again.
The 34-year-old Jersey Shore alum announced her engagement to Christian Biscardi in March 2019, and while the pair has not publicly confirmed a breakup, they have both recently unfollowed each other on Instagram.
Additionally, Christian, 31, appears to have deleted any sign of Sammi from his Instagram page. Sammi's most recent Instagram post with him on her own account dates back to February 2020, although she included their Christmas card photo for her YouTube video entitled "Sammi's Favorite Holiday Traditions" in December 2020.
E! News has reached out to Sammi for comment and has not heard back.
On March 5, 2019, Sammi posted a photo of Christian down on one knee to announce their engagement after the couple had been dating for two years.
"I'm completely overwhelmed with happiness," she wrote in the caption at the time. "Yesterday was the best day of my life! I get to marry my other half, best friend and soulmate. [heart emoji] I look forward to spending the rest of my life with you @_biscardi I love you!!"
Prior to dating Christian, Sammi and former Jersey Shore co-star Ronnie Ortiz-Magro had an on-and-off romance for years. They initially connected on the first season of MTV's Jersey Shore that premiered in 2009.
In March 2018, she took to Instagram to explain why she had opted not to participate in the TV spinoff Jersey Shore Family Vacation.
"I am not the same person as I was when I was 22," she wrote back then. "At 31, I am currently extremely happy in every aspect of my life and want to avoid potentially TOXIC SITUATIONS."
Ronnie, 35, was arrested on April 22, 2021 in Los Angeles on charges of intimate partner violence with injury. At that time, he was on probation stemming from a previous domestic violence case involving his ex-girlfriend, Jen Harley.
Last month, the L.A. City Attorney's office told E! News that it had filed a probation violation against Ronnie, rather than filing a new case.
