In this week’s all-new episode of The Real Housewives Ultimate Girls Trip: Roaring 20th, Vicki Gunvalson, Kyle Richards, Luann de Lesseps, Teresa Giudice, Porsha Williams, Gizelle Bryant, and Lisa Barlow are leaving Orange County for Beverly Hills! However, along the way, Giudice has to take care of some unfinished business with Gunvalson.

In this exclusive clip from the next installment of RHUGT, the girls are all together in a luxury van heading to 90210. “She is mean sometimes,” says Gunvalson, talking about a mystery Housewife. She adds: “Not all the time; I can be mean too.” Hearing that statement, Giudice can’t help but cringe and jump into the conversation. “Vicki, you were mean to me yesterday.”

Suddenly, the other women in the van go quiet. “What’d I do?” asks Gunvalson earnestly. “You were saying that I changed the most,” says Giudice, referencing Gunvalson’s reaction when she saw all of the Housewives’ first season portraits on the yacht. The camera then cuts to Giudice in her confessional. “See, this is how I am. Sometimes I have to process things. Like, it doesn’t hit me at that moment.”

The editors then treat viewers to a montage of Giudice during yesterday’s activities. As Giudice fixes her hair on the yacht, they add Giudice’s interior monologue. “Was she really trying to, like, insult me?” Then, the editors cut to Giudice sitting in the back of the SUV on her way to ‘80s night, lost in thought. “Oh, it was insulting,” opines Giudice’s inner voice. Back in the confessional, Giudice confirms her findings. “She was being rude.”

In the van, Gulvanson tries to do damage control. “You’re beautiful,” exclaims Gunvalson. “I think I’ve aged gracefully,” says Giudice as she moves on to her next grievance point. “At one point, you yelled, ‘pay your taxes!’” At this point, the women shift uncomfortably, knowing that Giudice believes Gulvanson was referencing one of the reasons why she briefly went to prison.

“I wasn’t referencing you actually,” explains Gulvanson. “I was referencing somebody else in my cast.” Stunned by Guvanson’s likely false omission, de Lesseps jumps in. “But you were looking at her,” she declares, gesturing towards Giduice. “I don’t even want to relive this,” snaps Giudice. “This happened 10 years ago.”

In the middle of Giudice’s sentence, Gulvanson interrupts her and lurches forward to point at a store: “Okay, this is a great clothing store. It’s all high-end Gucci, amazing Valentino.” Needless to say, the other women are shocked by Gulvanson’s behavior. “I’m having a Ramona moment,” says de Lesseps, alluding to her former RHONY castmate (and notorious narcissist) Ramona Singer. “She is so rude.”

Back in the present, Giudice realizing that she’s getting nowhere with Gulvanson, wraps up her thought: “So anyway, I don’t want to talk about what happened 10 years ago either because that’s what gives me anxiety.” In her confessional, Giudice explains further. “I don’t like to keep getting reminded of that. It’s a cross that I have to carry. It’s been 10 years. I want to take that cross off already.”

Guidice ends her confessional by saying, “So, thank you, Vicki. Thanks for being a bitch.” Has Giudice spoken her piece with Gulvanson or will there be another conversation in their future? Tune in to The Real Housewives Ultimate Girls Trip: Roaring 20th this Sunday at 9PM on Bravo and find out!
