During Tuesday night's reunion show, Camille Grammer told Andy Cohen and the ladies that she believes that Lisa Vanderpump failed to show up at the reunion and quit the show because of Brandi Glanville's return.

"She's pissed about Brandi [Glanville]," Camille told them. Brandi returned to the show earlier this season and said that Lisa "for sure" leaked the story about Dorit Kemsley to RadarOnline during a meeting with Denise Richards.

"[She's pissed] that Brandi showed up on the show. Absolutely. [Brandi] 's her archenemy. She feels so betrayed." 

The ladies denied that Brandi could have been the reason for LVP's absence.

"I'm just assuming and I could absolutely be wrong, but she felt that throughout this season, you've had her back, Denise [Richards]. And with you talking to Brandi — Brandi's her archenemy," Camille added.

After viewing the second part of the reunion, Brandi responded to Camille's claims via social media:

"I am NOT LVP's arch enemy!!That is absolute insanity. Trust & believe that is UNTRUE!!I I adore @DENISE_RICHARDS after meeting her at a dinner party for our mutual agent! NTM 95% of our conversation was not about lvp at all. Nope @TheRealCamilleG I don't buy it! She knows for a fact that I'm a proper f*cking person & that I do the RIGHT thing when I'm suppose to. We may not be friends but I'm not LVP's #1enemy".

Brandi then continued, "Let me be clear, LVP& I have a past that we will not recover from but I refuse to let @DENISE_RICHARDS be called out for provoking anything! I was on ONE episode of an entire season where the women had their own separate issues with her. That's f*cking it. It's clear to me that if certain people feel that they are going down they have the need to take everyone down with them. If I had done that the ENTIRE housewives world would be 'Shook.' I'm not that person & that's not how I'm raising my boys."
