Yep, she went there. Sonja Morgan alleges that her costar Dorinda Medley does drugs in a preview for the dramatic Real Housewives of New York City season 8 reunion, which airs Wednesday, September 7.

In the nearly two-minute teaser above, Medley, 51, expresses her disappointment at being accused of having an issue with substance abuse: “Why are you insinuating that you know I do drugs? That’s a horrible thing.”

Without hesitation, the Tipsy Girl founder, 52, fires back, “Everybody knows you do drugs!”

Prior to sitting down with the ladies of RHONY, Morgan opened up to Bravo head honcho Andy Cohen backstage (as seen in the sneak peek) about feeling the urge to go in on her castmates. “I have dirt on all the girls. I just hope I don’t go there,” the reality personality — who joined the hit series in the third season, which originally aired in 2010 — explains. “But I’m starting to, after all these years, have resentment.”

Aside from Morgan and Medley’s friction, there’s plenty of other explosive moments during the ’wives get-together in the Big Apple. Longtime frenemies Bethenny Frankel and Luann de Lesseps are at it again, throwing heated insults at each other left and right.

Frankel — who memorably branded de Lesseps, 51, a “slut, liar and a hypocrite” earlier this season following an argument about the Countess’ participation in the genesis of Frankel’s Skinnygirl brand name — decides to take aim once again at the Class With the Countess author. 

“You were born a liar and you will die a liar," she sneers at de Lesseps, to which the “Chic C’est la Vie” singer replies, “You’re a horrible person.”

As viewers recently witnessed, their feud came to a head when Frankel exposed de Lesseps’ fiancé Tom D’Agostino Jr.’s affair out of concern for the mom of two. However, de Lesseps decided to stick it out with her groom-to-be — a decision that has apparently done nothing for her friendship with Frankel.

Watch the video above. Part 1 of The Real Housewives of New York City season 8 reunion airs on Bravo Wednesday, September 7, at 9 p.m. ET.
