"The Real Housewives of Beverly Hills" is expected to return to Bravo later this year, and there have been reports that a casting shake-up has taken place. It has been claimed that some Housewives from the previous season have been asked to return, while two of the ladies are said to be out.

According to Tamara Tattles, Kyle Richards, Lisa Vanderpump, Lisa Rinna, and Erika Girardi have all been asked to return for season 7 and that all of them have allegedly accepted their contracts. However, season 6 newbie Kathryn Edwards is said to have not been given a contract, while Yolanda Foster, is also allegedly out.

Reality Tea reports that after her divorce from David Foster, no one is interested in Yolanda's Lyme disease storyline. The website speculates that not one of the other women campaigned to get the former model back on the show for the upcoming season. As a result, Yolanda is said to be furious, and Tamara Tattles says that there is a prediction that the star may pull a last-minute stunt in order to convince producers to bring her back.

Meanwhile, Eileen Richards is said to have been asked back for the new season, but she has allegedly been demoted as a "friend" of the Housewives. As for Kim Richards, the former child star is being considered as a "friend" of the Housewives as well, but the network is allegedly upset with her as she reportedly had a relapse while filming "The Mother/Daughter Experiment."

It appears that some new faces will be featured on the show as four women are said to be testing for the newly opened slots on RHOBH. Reality Tea reports that one of them might be Sydney Holland, and sources told the site that Holland officially pitched herself to Bravo by creating a "sizzle reel."

"The Real Housewives of Beverly Hills" is expected to return in December on Bravo.
