“Oh shut up Denise,” Grammer, 50, replies.
“Don’t tell her to shut up Camille, don’t, don’t. She's my friend,” says Lissa Rinna.
“I know she’s your friend but I don’t like her,” says Grammer.
“Just calm down for f**k’s sake,” says Richards as her fellow housewives look on, stunned by Grammer's wild behavior.
“I don’t like her!” Grammar continued yelling. “She told me to tell my daughter she was a f***ing liar.”
“What are you talking about?” asks Richards, 48.
The screen then flashes to a scene from the show during which Grammer accused Teddi Mellencamp of ignoring her daughter when she said hello. At the time, Richards told Grammar to tell her kid it had all been a misunderstanding, to make her feel better. She and Grammar then got into a nasty fight about parenting, during which Grammar accused the Wild Things actress of making her daughters “feel like s**t.”
Back on the reunion set, the ladies continued to argue about the fight, with all of them siding with Richards and voicing their concern from Grammer.
“What is wrong with you?” asks Richards. “Honest to god, you need to go take a second, because this is not good.”
“When you were sitting there at lunch with Camille and she was trash-talking everyone, what was going through your mind?” Cohen, 51, asks Richards.
As she starts to answer, Grammer gets up from the couch, saying “So this is truly a set up.”
The ladies and Cohen watch on, confused, as Grammer unzips her dress while walking back to her dressing room and cursing at her costars.
“Is she on something?” Richards asks. “She’s f***ing nuts.”
“What’s the set up?” Cohen asks.
The cameras follow Grammer backstage, while an assistant holds up her unzipped dress.
“Nasty b***hes” she says, slamming the door behind her.
