'Real Housewives of New Jersey' clash in reunion teaser - video
Conflict between Teresa Giudice and sister-in-law Melissa Gorga erupts in the new clip, when Gorga accuses Giudice of starting rumours that she was once a stripper.
Jacqueline Laurita jumps to Gorga's defence, declaring that her former best friend Giudice is "going to hell" for her behaviour.
A second teaser sees Giudice as the recipient of a tirade from Carolina Manzo after an insult about Manzo's "blubber".
The two have argued on many occasions in the current Real Housewives of New Jersey season, but Manzo has insisted that she is right to tangle with Giudice.
"Understand one thing: I have never attacked her, never said anything that wasn't in response to something she said to me. I do get agitated and I'm only human," she wrote in her blog in August.
"If [viewers] think I'm a bully, that's fine. I just want my husband and kids to love Caroline Manzo and I'm good. If I have to be the most hated woman in the country because of that moment, so be it. That's my truth.'
The Real Housewives of New Jersey reunion airs Sunday at 10/9c on Bravo.
