This Just In:

Ronnie Ortiz-Magro is not the only Jersey Shore cast member involved in a controversial relationship.

We all know about the many ugly issues between Ronnie and Jen Harley, of course, but a newly-released trailer for upcoming episodes of this popular program makes it evident:

Things may not be perfect between Jenni Farley and boyfriend Zack Clayton Carpinello, either.

In an explosive look at what's on tap for these often-drunk and chaotic reality stars, Angelina Pivarnick accuses Farley's young lover of making a move on her.

“What happened in Vegas?” Angelina’s fiancé, Chris Larangeira, asks as a flashback clip plays of Zack greeting her with a hug in the video featured here.

In response, Angelina admits:

“I just feel his hand go right on me,” as she slaps her hand on her butt, much to Chris’ shock and irritation.

Later, Angelina says her engagement is in jeopardy, presumably as a result of this alleged incident.

From here, the stars attempt to get to the bottom of this romantic mess.

Chris refers to Zack as a “clown” and threatens to “knock this guy’s teeth out.”

In a confessional, Vinny Guadagnino says he is “seriously worried about the next time we’re gonna be together.”

"It's like Zack's word against Angelina's," Pauly D says in a deep conversation with Vinny and Ronnie.

Meanwhile, Jenni claims at one point that everything is reversed and that Angelina is the one who acted inappropriately with Zack.

"We need to figure out what happened," Snooki says calmly, to which Jenni fires back, "She f-cking kissed him!"

Cut to a group meal and Angelina pressing Jenni over whether she's "trying to be grimy now," which prompts Jenni to jump up in a blazing fury and pound on the table.

She repeats, "Grimy?! Grimy?!" in stunned disbelief.

Important takeaway here: Never refer to Jenni Farley as grimy apparently.

“Now it’s an all-out war,” Vinny says.

For the record:

Angelina and Chris have been engaged since January of 2018, while JWoww started dating Zack in March amid her divorce from Roger Mathews, which the ex-couple finalized in August.

“I never in a million years thought I would be dating someone younger than me,” JWoww told Angelina and Mike Sorrentino’s wife, Lauren Sorrentino, on a recent episode, adding in extreme detail:

“We’re completely different. … Not my style at all. But then he turns into this fcking monster in bed. I was like, ‘Are you an escort? What’s going on?’ It wasn’t normal.

"I had to look up positions and stuff."

Well... okay then!
