"The Real Housewives of Beverly Hills" is about to return for its seventh season on Bravo, and ahead of the reality show's upcoming installment, recent reports indicate that some of the original cast members are feuding with newcomer Eden Sassoon.

Sassoon, who is the heiress to late hair and beauty icon Vidal Sassoon's empire, was cast as a friend of the Housewives for season 7, and according to Radar Online, some of the regular cast members were not thrilled about this at all.

"Lisa Vanderpump, Lisa Rinna, and Kyle Richards really do not like Eden at all," said a source to the media outlet. "Lisa Rinna, especially, does not get along with Eden."

In a recent interview, Rinna reportedly made her opinion clear about Sassoon when she said, "I was a big fan of her dad's!" The insider claims that some of the cast members say that the heiress "acts like the first big fortune heiress to ever be on RHOBH."

The source said that there's talk of Sassoon being insincere and that she was trying too hard to be accepted. Meanwhile, another insider said that the ladies think that the newcomer wants nothing more than to be a regular Housewife just like them.

It was previously reported that Richards slammed Sassoon during a recent photo shoot for Cozi TV. An on-set source told Radar that the former actress was talking about the new season, claiming that everyone "absolutely hates" Sassoon.

Based on the reports, it looks like there will be a lot of tension up ahead when the show returns next month. Last season, the majority of the ladies had a feud with Yolanda Hadid, who left the series after the sixth season.

Apart from Rinna, Vanderpump, Sassoon, and Richards, the new season of "RHOBH" will see the return of Erika Girardi and Eileen Davidson. Vanderpump's good friend and fellow Brit, Dorit Kemsley, will be joining the show as one of the Housewives.

"The Real Housewives of Beverly Hills" season 7 premieres Tuesday, Dec. 6 at 9 p.m. ET on Bravo.
