Lisa Rinna, Kyle Richards Deny Bullying Lisa Vanderpump, Call Her Out for Not Filming with Them
Inside Camille Grammer's Hawaiian Wedding

Rinna criticizes Vanderpump for retreating from filming following her brother's suicide, saying, "If you sign up to do a job, you do it."

A few of "The Real Housewives of Beverly Hills" are calling out Lisa Vanderpump for refusing to film with the rest of cast, while denying accusations that they've been "ganging up" on her all season.

The furor erupted on Instagram over the weekend, as Kyle Richards, Lisa Rinna, Dorit Kemsley and Teddi Mellencamp attended Camille Grammer's wedding in Hawaii. Vanderpump was MIA, leading to a ton of show fans asking why she wasn't there in the comments of photos the other women shared.

"Why do YOU guys always [gang] up on LVP? This show will suck without her, but I'm sure she will be in all your mouths," one of Kyle's followers commented on a photo of Richards and Grammer on her wedding day.

"NOBODY has ganged up [on] anyone. Any report of that is an outright lie," Richards responded on Monday. "LVP has been invited to every single event that we each have been invited to. If she chooses not to come then that is her choice. Anyone trying to sway the public to believe anything else is not being honest."

Vanderpump posted a photo herself on Sunday, showing her at a Dodgers game in Los Angeles. In her comments, another fan accused Lisa's costars of "trying to deflect away from themselves" with the drama.

"This season of @realhousewivesofbeverlyhills is clearly a massive gang up of bullying against you and I think it will be their biggest mistake," the commenter continued. "That show will not survive to be the show it was without you. #factsarefacts"

Vanderpump clearly approved of that sentiment, as she replied, "Someone's paying attention."

A Bravo fan account also caught the eye of Lisa Rinna, after Elle's Juicy Scoops shared a side-by-side of Vanderpump at the ball game and everyone else celebrating Camille's nuptials. The comment on the photo: "I predict a season with silly fights, little friction and a lot of snooze in between. LVP grieving the loss of her brother in her own way, being distant and absent here and there, throwing some shade, new alliances and attempts to gang up on LVP."

First, Rinna asked, "Why hasn't Lvp filmed with us for over 6 weeks? I have no beef with her. Who does that? Who doesn't show up for work?

Rinna also said the loss of a family member should not be a reason to avoid filming and added that she and her costars are not bullying LVP. Vanderpump's brother, Mark, died after a suspected overdose in April.

"I too lost my father while filming and I completely understand that everyone's grieving process is just that their process. We have all reached out to her and we are all there for her. She has chosen to not film with us," wrote Rinna. "I too lost my sister to an overdose I have great empathy and I have been there. If you sign up to do a job you do it. No matter what. That's show biz."

"I did it. Eileen did it when her mother passed away the day before the reunion. You show up or if you can't then you say I can't and I'm going to take this season off to heal," she continued. "But please don't make any of us out to be bullies. We are not. We are here to film a tv show that we all signed a contract to do. We wish LVP only the very best in her time of mourning."

A premiere date for Season 9 of "RHOBH" has not yet been announced.
