As if this season of The Real Housewives of Beverly Hills hasn’t had enough drama… In a preview of a new episode with the cast in Rome, Italy, Denise Richards calls out all of her co-stars for being “Mean Girls.”

Throughout the season, the rest of the cast has had issues with Richards and her husband. However, it has all come to a boil during the trip after ex RHOBH star, Brandi Glanville, shared with Kyle Richards and Teddi Mellencamp that she had an affair with Denise right before leaving for the trip.

After confronting Denise about the rumor, more drama ensued and in the preview, for the episode the ladies are at dinner when she shares, “This has been, probably, the worst trip I’ve ever been on in my entire life, that is the truth.”

Leading to some ladies asking for clarification and accusing Kyle of bringing up the Glanville rumor, “You drag in Brandi, that’s not f—ing cool, and you know what, it has gotten to the point this is the god’s honest truth-where it is Mean Girls.”

The ladies are visibly angered with once again being labeled ‘Mean Girls.’ However, Erika Jayne in confessional shares she is proud to be a ‘Mean Girl’ because it means she is saying how she feels and standing up for herself.

As the ladies continue to talk, Dorit Kemsley attempts to speak, but as she begins, Garcelle Beauvais abruptly states, “I want to hear you, but I’ll be back.” Leading Kyle to say, “What’s up with the dramatic exit?”

If this short clip is any indication of how the rest of the episode will be, it will be a must-watch. The Real Housewives of Beverly Hills airs Thursdays at 9 p.m. on Bravo.
