Watch Teresa Giudice and Kim D.’s Tense Fight at the Posche Fashion Show on ‘RHONJ’ (Exclusive)

Bravo

The drama goes down on Wednesday’s all-new episode.

Nothing good ever happens for The Real Housewives of New Jersey at the Posche fashion show.

ET has your exclusive first look at Teresa Giudice and Kim De Paola (aka ‘Kim D.’)’s expletive-filled exchange at this year’s event, which keep in mind was in the name of charity. Problem is, Kim started spreading rumors that Teresa was being unfaithful to her husband, Joe, while he is behind bars. Kim even told the rumors to Teresa’s co-stars and friends Siggy Flicker and Dolores Catania, who previously agreed to walk in the charity fashion show -- and kept their commitment even after hearing what Kim had to say about Teresa. Of course, this isn’t the first time Kim has spoken out about Teresa’s marriage.

“Kim, you’re so f**ked up,” Teresa tells her nemesis. “You talked about [his alleged cheating] two years ago. Did you see him f**king another girl?”

“No, I did not,” Kim replies. “Thank god I didn’t see that, ‘cause I felt it.”

After that confusing comment, Kim adds, “I have girls, models here that saw you, you’re going out to clubs every freakin’ night.”

“Kim, you’re the queen of going out,” Melissa interjects, but Kim comes back quick with, “Wait a minute, I don’t have a husband and kids!”

“There’s no chain on my foot,” Teresa fires back. “I can do whatever the hell I want. I go out with Siggy, I go out with Dolores and who gives a f**k what I do?! It’s my f**king business.”

“I knew that this rumor was a bunch of bulls**t,” Melissa notes in a confessional. “Kim basically just admitted that the whole basis for her trying to destroy Teresa’s marriage is someone saw her out at a club, and Siggy and Dolores, that’s still not enough to piss them off? I mean, come on. It’s disgusting.”

“I want to f**king straighten you out right away,” Teresa spouts, starting to grab at something to seemingly throw at Kim.

“Nobody straightens me out!” Kim D. shouts back. “And I don’t give a s**t about any of you. You’re white trash. You’re the one that was in f**king jail, not be, b***h! If you throw something at me, girl, you’re leaving in handcuffs and going back where you were.”

That comment sets off not only Teresa, but surprisingly season eight newbie Margaret Josephs. The self-professed “powerhouse in pigtails” then unleashes on Kim, screaming at the boutique owner to, “Don’t ever speak to her that way!”

Kim D. then stands up to literally confront the girls face-to-face, asking Danielle Staub if she’s now Teresa’s “soldier.” That confrontation doesn’t get very far, though, because Teresa interrupts in order to finish her thoughts from earlier as she proclaims, “I’m here for a reason!”

“I know what Kim D. is capable of, but I also know what Teresa’s capable of,” Danielle remarks in a confessional. “And I’m so glad to be on Teresa’s side of the fence this time.”

“You know what Posche stands for?” Teresa asks Kim D. “Piece of s**t, cokew***e homewrecker every day.”

“Listen to me, Teresa,” Kim growls back. “You don’t want to go there with me.”

“OK, let’s go,” Kim replies. “Let’s go baby, I’m here.”

You’ll have to tune into The Real Housewives of New Jersey on Wednesday at 9 p.m. ET/PT on Bravo to see what happens next -- but to hold you over, the cast gave ET some insight into the epic night.

“We made a commitment,” Dolores says. “We went there to do what we were supposed to do ... I don’t know why we were told not to be a part of something, when [Teresa has] always, in the past [gone] … There’s a lot of hypocrisy, there’s a lot of test of friendships.”

“Believe me, I did not want to go,” Teresa admits. “But it was for a good cause. It was for a charity event ... I didn't know [Kim] really wanted to come after me until this season. She was really always going after Melissa … and now, all of a sudden, I don't know. That's a question that you would have to ask her.”

“I get nervous when that Teresa comes back,” Melissa shares. “I had no desire to go to [the fashion show], and I was, like, pulled there. Pulled there! I went to support my sister-in-law with that one. So, let's just leave it at that and say someone's gonna tell me I was right once again.”
