JWoww has called it quits with her boyfriend after finding out that he flirted with one of her co-stars ... and wasn't informed until it aired on TV.
The move by JWoww comes hours after she witnessed her boyfriend making moves on Angelina Pivarnick in Las Vegas while JWoww was passed out.
Angelina didn't exactly refuse any flirting advances by Carpinello, but later commented in a confessional that he was pushing the "boundaries."
After the episode aired, JWoww took to social media and admitted she was totally unaware of the incident.
"After seeing tonight’s episode I’m pretty hurt. I feel disrespected by someone I called a friend and by someone who stated they loved me. For 5 months I was naive, probably laughed at and made into a storyline that will forever haunt me. My heart hurts on so many levels."
She added, "One thing I learned from tonight’s episode is to know your value. Don’t ever lower your standards."
JWoww also clapped back to fans about Angelina's part in the flirting, explaining, "She was all over him too... I saw her ass in his face. Real friend there. She stirred the pot knowing it would end up on tv."
The reality star further railed on Angelina, explaining, "If she was a true friend, she would've checked him and then came straight to me. She lived for the drama and straight disrespect."
The drama will still play out on upcoming episodes of "Jerse Shore: Family Vacation," but unless Zack finds a way to make things right he probably won't be returning for another season on MTV.
