'Real Housewives of Beverly Hills' Season 9 Spoilers: Lisa Vanderpump Isn't 'Thrilled' to See Castmates at Denise's Wedding [SNEAK PEEK]

Wedding bells will ring on the upcoming episode of Real Housewives of Beverly Hills. However, the happy union of show newbie Denise Richards and Aaron Phypers, obviously, won't come without a little bit of drama, compliments of her catty castmates.

Following Lisa Vanderpump's heated exchange with Dorit Kemsley and Teddi Mellencamp at Camille Grammer's 50th birthday party last week, the reality star isn't necessarily excited to encounter her cast mates again at Denise's wedding on Tuesday night's episode 7. Still overwhelmed by her latest run-in with the women, LVP worries there may be more confrontation headed her way at Denise's beach-side wedding in the episode sneak peek.

"I'm not thrilled to see the other women, and after Camille's birthday, I hope that there's no repeat of the kind of intense animosity that transpired there," Vanderpump said in a confessional.

The restaurateur isn't the only one hopping the women can keep their claws at bay during the wedding. Lisa Rinna is also no longer interested in hearing the Lucy Lucy Apple Juice narrative. In the clip, she tells Erika Jayne she'd be "happy if we never talked about" the dog again, but she knows "that's just a pipe dream."

"That dog is fine. Move on. It's Denise's wedding and no one should do one thing. Everyone should be on their very best behavior," she said.

However, there may be more drama brewing between the cast beyond Vanderpump, Dorit and Teddi's issue surrounding the animal. In a second clip, Dorit finds out more incriminating information circling about her, and her husband Paul "PK" Kemsley seems to think LVP is behind it.

"Lisa must know that the truth is gonna come out," PK said.

"You think this is Lisa?" Dorit asked, while later telling green-screen cameras, "This is a whole other layer of betrayal."

Real Housewives of Beverly Hills airs on Bravo on Tuesday at 9 p.m. ET.
