may be facing off against her husband Paul Nassif
in divorce court off-camera, but the Real Housewives of Beverly Hills
star has another adversary on-screen for the show's upcoming third season: her former neighbor and BFF Lisa Vanderpump
Recall, of course, that the ladies began bickering toward the end of last season. (Maloof's chef, Bernie, especially took issue with Vanderpump, her husband and their dog, Giggy.) But the tension boiled over during the reunion specials
when Maloof accused Vanderpump of selling stories about her in the tabloids.
Apparently the ladies haven't made up – and now PEOPLE has an exclusive first look at some of their drama in advance of the Bravo show's premiere (Nov. 5, 9 p.m. ET). Oh, and drama magnet Taylor Armstrong is involved, too!
In the clip (watch it above), we see Taylor reveal to Adrienne that Lisa is throwing an anniversary party for her Beverly Hills eatery Villa Blanca
and, well, Adrienne is the only one of the Housewives not invited. (Even newcomer Yolanda Foster
scored an invite!)
"I thought we had moved on, and apparently she's still upset," Adrienne says in an interview during which she calls Lisa's actions "mean girl-ish" and adds, "Of course, being left out is hurtful."
Taylor, for her part, is contrite, though that doesn't stop her from discussing the party. "I feel like a big jerk for letting the cat out of the bag," she tells Adrienne about the "awkward" situation she created.
