'RHOC' : Shannon Beador Says 'the Liar Story Has to Stop' amid Fight with Braunwyn Windham-Burke

Shannon Beador and Gina Kirschenheiter are still grappling with the aftermath of their explosive fight with Braunwyn Windham-Burke that occurred at Shannon's housewarming party.

In PEOPLE's exclusive sneak peek at Wednesday's episode of The Real Housewives of Orange County, Shannon and Gina attend lunch at Elizabeth Lyn Vargas' house. Their conversation quickly turns to the party and the screaming match that went down between Gina and Braunwyn.

The fight began when Braunwyn said Shannon called Gina's condo "sad and depressing." Shannon denied that she said anything disparaging about Gina's home, and the building tension resulted in a confrontation with Gina and Braunwyn, who recently opened up about being an alcoholic.

Braunwyn, 43, stormed away from the fight and threw her glass into the pool after Gina, 36, called her a "sloppy chihuahua," to which Braunwyn responded with, "I'm 30 days sober, bitch."

"Have you seen or spoken to Braunwyn since the party?" Shannon asks Elizabeth in the sneak peek, who shares that she texted her afterwards to say, "I didn't realize you were going through such hard times. I hope you're well and I'm thinking of you."

"I hope she gets well, too," Gina says, before adding that supporting Braunwyn is "tricky" for her. "I'm the person she's choosing to put her s--- on because she doesn't want to deal with it. Maybe she's just f---ing floundering."

"There's a lot of judging going on — it's not nice, it's not fair," Elizabeth says of Gina's comment in a confessional. "I mean, to each his own, I just think she should be a little more sensitive."

On last week's episode of RHOC, Braunwyn attempted to smooth things over with Gina, inviting her to attend an Alcoholics Anonymous meeting with her.

"So that means if you guys get along, you're going to maybe come to her vow renewal?" Shannon, 56, asks Gina at lunch, referring to Braunwyn's vow renewal in Palm Springs.

"I declined the invitation," Gina says.

Braunwyn previously personally called Shannon to make sure she was coming to the vow renewal, despite their ongoing disagreement.

"She called me and said, 'I know it's going to take time to move past our issue, but I want you to come,'" Shannon tells Gina and Elizabeth. "She invited all of our kids and all our kids are excited to go so what do I do? Tell my kids, 'No, Mom got in a girl fight, so now we're not going to be able to go?'"

"I don't know what Braunwyn's expecting," Shannon later adds in a confessional, confirming that the tension between her and her friend is not over. "You call me a liar and I'm supposed to say, 'Oh, let's go be fine?' Time is only going to tell, but the liar story has to stop."

The Real Housewives of Orange County airs Wednesdays (9 p.m. ET) on Bravo.
