Who Was She Again?

People are looking for a mini "Jersey Shore" refresher course -- specifically about Angelina Pivarnick -- after the Jenni "JWoww" Farley split from her boyfriend, Zack Carpinello.

She's Been In and Out Of the Group

Pivarnick was one of the original cast members of "Jersey Shore," joining Farley, Mike "The Situation" Sorrentino, Paul "DJ Pauly D" DelVecchio, Sammi "Sweetheart" Giancola, Vinny Guadagnino, Ronnie Ortiz-Magro and Nicole "Snooki" Polizzi at the beach house.

She was only there briefly, and left after episode three. She came back for Season 2 but again left after getting into fights with The Situation and Polizzi.

Pivarnick, now an EMT and engaged, continues to cause trouble on "Jersey Shore: Family Vacation."

Honestly, What Is She Doing There?

Apparently, on the latest episode of "Jersey Shore: Family Vacation," while JWoww was passed out after a night of partying, Carpinello was seen touching Pivarnick's butt and hugging her while in a Las Vegas club.

Pivarnick says the whole thing was Carpinello's fault:

"One minute he's asking me about my sex life, the next minute he's grabbing me!"

"He doesn't know what boundaries are. This is gonna be a problem."

JWoww 'Hurt' After Pivarnick / Carpinello Incident

JWoww took to Instagram to express her anger, saying she was "kept in the dark" about the whole thing. She also says she feels hurt and disrespected by a friend and her boyfriend.

"One thing I learned from tonight's episode is know your value. Don't ever lower your standards," JWoww said.
