Sammi "Sweetheart" Giancola was a hot topic during Thursday night's debut episode of the "Jersey Shore" reboot, "Jersey Shore: Family Reunion," but only because she wasn't there. As fans have likely heard by now, Giancola chose to skip the reunion season with her co-stars and is currently enjoying her private life at home with boyfriend Christian Biscardi.

Throughout the episode, Giancola's absence was addressed and at one point, her former boyfriend, Ronnie Magro, suggested Giancola skipped out on the reunion because she wasn't friends with the cast and didn't have their backs.

Magro also pointed out that he chose to participate with his former co-stars, despite the fact that he and girlfriend Jennifer Harley had a child on the way during filming (the baby girl, Magro's first child, arrived earlier this week).

Christian Biscardi discusses negativity amid 'Jersey Shore' premiere

Around the time the episode aired, Giancola took aim at Magro on Twitter by liking a number of messages about his shadiness sent by her fans and followers as Biscardi seemingly criticized the negativity of the show on his Instagram page. In the caption of a post shared on his page on April 5, Christian Biscardi said there was "too much negativity in the world." Meanwhile, Giancola liked posts about moving on from her relationship with Ronnie Magro.

While Biscardi didn't mention the MTV reality series on the show, his girlfriend didn't hesitate to get in on the action on Thursday night on Twitter by not only liking posts about the series but also by telling her fans and followers that she loved her girl Deena Nicole Cortese. During the premiere episode, Cortese spoke out in Giancola's defense as her co-stars questioned her feelings toward her former co-stars.

Around the time of his "negativity" post, Biscardi shared a throwback photo of himself and Giancola and applauded his girlfriend's elegance. "It’s nearly impossible to come across someone with the elegance and class that this person does," he wrote in the photo's caption.

"[Sammi Giancola] truly has the biggest heart out of anyone I have ever met and deserves all of the good things in life."

In response to her boyfriend's kind words, the ex-reality star wrote, "My best friend. My other half." She then added, "I love you with my entire soul."
