'RHOBH' Tea Time: Dorit Kemsley Keeps Lisa Rinna 'Coke Den' Feud Alive After Vegas Apology

On Tuesday's episode of "The Real Housewives of Beverly Hills," Dorit extended an olive branch by agreeing to let her husband, PK, invite Rinna to her birthday dinner. Rinna was so grateful for the invite, she made a speech at the dinner, thanking the Kemsleys for the invite and toasting to a fresh start with the pair.

But all that went out the window when Dorit and PK invited new housewife Teddi Mellencamp Arroyave and her husband, Edwin, to their home for dinner -- and the can of coke, if you will, was reopened behind Rinna's back.

"So, I want to just tell the guys one thing, that we had a dinner party here with Rinna a year or so ago, and it was the first time I ever met her," PK told Teddi and Edwin at the start of the meal. "She was so nice, and we had such a nice evening. After evening, it clearly wasn't as nice for her as it was for us because she basically left and just basically attacked Dorit, attacked me, attacked the whole evening."

The attack -- verbatim -- was, "Were people doing coke in your bathroom?"

"He thinks Lisa Rinna is schizophrenic," Dorit told the Arroyaves. "He had said this when I came back from a girls' trip to Hong Kong, and I was really distraught. And I said, 'PK, I do not know where this came from. I mean, one morning, she invited me into her room for coffee and things were fine, and then that night, I was on a boat and it was like a missile attack.' It was designed to hurt me. She once again got in my face -- Lisa Rinna with the 'F-ck you!' She's one person one minute, and then she's another person another minute. She's got rage and regret, rage and regret, rage and regret. It's like, oh my God, someone you know -- a friend, nonetheless -- is capable of doing something so vicious to you."

"The fact that she would get up and give me a speech on my birthday is so preposterous that it's funny," Dorit added, waiting for a response from Teddi.

When Teddi said she was "shocked" to hear the story given how well Dorit and Rinna had been getting along, PK interrupted: "You wait, babe."

"I'm confused," Teddi later told Bravo cams. "You just had this big moment where you've forgiven each other, and now you're at a dinner talking about it again? That's not forgiveness in my opinion."

"The Real Housewives of Beverly Hills" airs Tuesday nights on Bravo.
