And who was again fanning the flames? None other than Tamra Barney.
"[My family beach house] holds so many family memories for me," said Rovsek, adding about the party, "I want it to be very elegant."
But the elegant dinner quickly turned into a debacle after Beador asked Barney if Dubrow's husband, Terry, had told her he "wanted to take the Beadors down."
"I don't recall that," said Barney.
"Tamra seems to have amnesia because she happened to tell me that," said Vicki Gunvalson.
When Beador decided to leave it alone, Barney decided to bring it up to the Dubrows over dinner.
"I think someone's stirring the pot here," hostess Rovsek correctly stated, just before the husbands began to battle.
"You're hearing I want to take you down?" asked Terry. "I don't want to take you down."
"You couldn't take us down," said Shannon's husband, David.
"You're right, David, I can't … because you're so tough," remarked Terry.
Cue a never-ending waltz to the beach house balcony, where Barney first swept away Dubrow before the Beadors joined the fray.
When Dubrow began to tell her version of how she learned of the Beadors' marital woes and why she ended up telling her friends about it, Shannon was breathing fire.
"You are not going to spin this on me!" Beador yelled, becoming emotional. "I came to you, Heather, in pain … It's my turn!"
When Dubrow continued, Beador stormed off the balcony and into the dinner party, screaming, "I've had it with her! You will all see the truth!"
When Barney – who also recently tangled with Dubrow – tried to stop her, Beador yelled, "I want you to get away from me!"
"My dinner party is in the gutter," sighed Rovsek, "and if Tamra didn't bring it up, we'd be having a good time."
The dinner drama continues on Monday's Real Housewives of Orange County airing (9 p.m. ET) on Bravo.
