If there’s one thing we’ve learned from watching this season of the Real Housewives of Beverly Hills, it’s that Kyle Richards and Carlton Gebbia shouldn’t be allowed in the same room. Though for a second we thought there might be some hope for these two crazy ladies (Kyle took off her necklace and gave it Carlton after she complimented her on it), it looks like it might be time to accept the facts.

In next week’s episode of RHoBH (Season 4, Episode 14), Kyle and Lisa throw a joint birthday party for Mauricio and Ken. (Wait. Did we miss the part where they became best friends again? When did that happen? Ugh, anyway...) Things seem to start out nicely enough: party planner Kevin Lee shows up with some synchronized swimmers who don’t actually know how to to synchronize swim. After she chastises Kevin for not delivering what he promised, Vanderpump Rules star Jax Taylor jumps in the pool to provide some much-needed entertainment. (He may make some questionable choices in his personal life, but homeboy’s got some abs!)

But then of course, all hell breaks loose. While talking over dinner, Kyle and Carlton get into it in front of their husbands and their friends.

“I have this feeling you’ve been talking shit about me,” says Carlton. “It was confirmed at my party with a few friends of mine. You were standing in the bathroom line and you said out loud, “Ew. I’m not going in this bathroom. Gross. [...] You’ve been making some nasty little snide remarks and I don’t like it.”

“I have been nothing but nice to you,” Kyle says in response. “You’ve been looking for something with me since Day One. I’ve gone out of my way to know you!”

And here’s where things get really riled up. When Kyle asks to speak after Carlton interrupts her, Carlton totally loses it. “Don’t you DARE command me! Don’t you f—king dare!”
