What Sammi 'Sweetheart' Giancola Has Been Up to Since Her Original 'Jersey Shore' Days

The reality star is set to appear in the current season of 'Jersey Shore: Family Vacation.'

Sammi "Sweetheart" Giancola anointed herself as "the sweetest b**ch you'll ever meet" when she appeared as an original cast member of the hit MTV series Jersey Shore. In the years since that show went off the air in 2012 after six successful seasons, Sammi has earned other sweet monikers, from sweetest fiancée to sweetest entrepreneur.

When the sequel Jersey Shore: Family Vacation was announced, Sammi was the only OG cast member who decided not to accept the vacay, citing she was "at a completely different place in my life right now." On March 11, Sammi announced she was back and though it's unclear if she’s back in a full-time capacity, she’s set to appear in the current season of Family Vacation, which returned with season 6 at the end of January and has aired seven episodes so far.

With her return imminent, ET takes a look at what Sammi's been up to since leaving Jersey Shore.

March 2018: Turns down Jersey Shore: Family Vacation

Sammi was the only member of the original Jersey Shore cast who declined to return for the sequel. At the time, Sammi announced she was in a different place in her life. When Family Vacation was first announced in 2017, Sammi was the only person not listed among the cast.

She would eventually take to Instagram and offer an explanation.

"I have chosen not to join the show this season because I am at a completely different place in my life right now focusing on my businesses and relationship," she wrote at the time. "I am not the same person as I was when I was 22. At 31, I am currently extremely happy in every aspect of my life and want to avoid potentially TOXIC SITUATIONS."

"However, it was a difficult decision as I love my roomies. I've decided to focus on me, my future and what truly makes me happy," she continued. "I will forever be grateful to Jersey Shore and everything it has brought to me! I've just decided to live my life for me these days." 

It's no secret Jersey Shore fans know she and her ex, Ronnie Ortiz-Magro, had an explosive falling out after their breakup. Ronnie would eventually take a step back from Family Vacation after five seasons.

"I have! I have [talked to her] and she gets the joke, she knows it was all in good fun, I'm glad too 'cause I was like, 'Shoot, I hope she doesn't hate me,' you know?" Pauly revealed at the time, before adding, "And I wanna say that thing is so heavy, it's like dead weight!"
