Get the soap! The Real Housewives of Beverly Hills' ladies head to a Moulin Rouge party in the Tuesday, February 2, episode, which leads to drama over a very divisive expletive, as seen in Us Weekly's exclusive first look.

The footage shows Kyle Richards, Lisa Rinna and Camille Grammer all arriving at the costume shindig, followed by newcomers Kathryn Edwards chatting with Erika Girardi about the fact that women tend to be judged more harshly than men do.

Edwards, 51, points out that women who are too nice get taken advantage of, to which Girardi, 44, replies, "And then if you're too mean, then you're a c--t."

But Edwards is quick to tell her costar never to use the C-word in her presence.

"That's the most disgusting word," the newest cast member of the hit Bravo series explains. "You're too beautiful to say that word."

But Girardi doesn't plan on changing her diction choice anytime soon.

"She's trying to correct me," Girardi tells the camera. "Number one, I don't care. Number two, I'm still going to use the word c--t every f--king time I can say it."

Watch the video above for their awkward exchange.

The Real Housewives of Beverly Hills airs on Bravo on Tuesdays at 9 p.m. EST.
