Lisa Vanderpump is reportedly fed up with the process of filming "The Real Housewives of Beverly Hills." As she allegedly remains at odds with a majority of her co-stars, including Teddi Mellencamp, Lisa Rinna, Erika Girardi, and Dorit Kemsley, a report on October 11 has claimed the restauranteur is actually refusing to film new scenes [VIDEO] for the upcoming season of the Bravo TV reality series.

“There’s so much drama surrounding this season of ['The Real Housewives of Beverly Hills'] already," an insider revealed to Hollywood Life on Thursday. "All of the ladies are mad at [Lisa Vanderpump] over the whole [Dorit Kemsley] dog incident, particularly [Kyle Richards] and [Teddi Mellencamp] as they feel Lisa is up to her usual tricks and set Dorit up."

Because the tension with her co-stars is said to be so high, Vanderpump allegedly refused to attend Camille Grammer's recent bridal shower in Los Angeles.

As the outlet explained, a number of the women were present during Grammer's celebration, including Kyle Richards, Teddi Mellencamp, Lisa Rinna, and the show's newest cast member, actress Denise Richards.

“[Lisa Vanderpump] is also refusing to film with them anywhere," the source said, adding Vanderpump is only currently speaking to Denise Richards.

After being accused of refusing to vacate her dressing room during a group shoot for "The Real Housewives of Beverly Hills" Season 9 by Lisa Rinna and Erika Girardi, the Hollywood Life insider explained Vanderpump had attempted to have her shoot moved to another day so she would not have to interact with her co-stars. The source went on to say that Vanderpump has isolated herself as she contemplates a potential exit from the show.

Just over a week ago, Vanderpump spoke to Hollywood Life herself. During the interview, she addressed the possibility of leaving the series, telling the outlet, “Everything comes to an end.”

"The Real Housewives of Beverly Hills" is expected to return to Bravo TV sometime later this year for Season 9, which Lisa Rinna says is deceitful [VIDEO], but a premiere date has not yet been set.
