Things are getting tense as “Real Housewives of Beverly Hills” Season 7 comes to a close. During episode 16, the group hurled accusations of relationship insecurity and drug abuse at one another. It seems that was the tip of the iceberg.

Previews for “RHOBH” Season 7, episode 17 show Kyle Richards, Eileen Davidson and Erika Girardi chatting in the aftermath of the junk boat blow up. While Kyle was “shocked” by Lisa Rinna’s attack on Dorit Kemsley, Erika called it “fair play.” She admitted she wasn’t the least bit sympathetic for Dorit, who spent much of the season discussing her white party wardrobe malfunction (dubbed pantygate) with anyone who would listen.

“I think Lisa Rinna totally realized how badly Dorit and PK treated me, and turnabout is fair play,” she said (via Us Weekly). “I’m not sure that Dorit is sincere. I’m not sure that neither she nor PK have understood what they’ve done, with this whole thing of, ‘Erika is trying to seduce me,’ or ‘Erika was trying to come on to me.’”

The drama began when the ladies of “RHOBH” gathered for an evening boat ride. After Erika erupted on Eileen for talking about her son, Lisa R. seized the opportunity to change the subject. With all eyes on her, Lisa R. questioned why Dorit left her and another guest alone at a dinner party months earlier.

“I’m just wondering were people doing coke in your bathroom?” Lisa R. asked matter of factly.

Dorit took offense to the question, assuring her “RHOBH” co-stars her home is not a “coke den.” Viewers have yet to learn where Lisa R.’s accusations stem from, but it’s possible the rumor was retaliation. Early in the Hong Kong trip, the QVC maven learned Dorit had suggested she had a pill problem, referencing her Xanax smoothie comment.

You’ll have to tune in to find out where this feud goes. Catch “RHOBH” Tuesdays at 9 p.m. EDT on Bravo.
