'RHOBH' Season Five Cast: All Housewives Have Signed On Except For Lisa Vanderpump

Lisa Vanderpump has not yet signed on for the fifth season of The Real Housewives of Beverly Hills.

According to a new report, Brandi Glanville, Kim Richards, Kyle Richards and Yolanda Foster have all signed with Bravo to return to the series for season five, but Vanderpump, on the other hand, remains unsure of her return.

“As of Friday, all the women except Carlton and Joyce have officially signed back on to the show," an insider revealed to AllAboutTRH on June 9. "Everyone keeps asking Lisa if she has really quit or not, but she is taking her time before she confirms her return.”

Throughout season four of The Real Housewives of Beverly Hills, Vanderpump was reportedly singled out by her co-stars, many of whom called her "manipulative" and accused her of leading other cast members to target Kyle Richards after reports claimed her husband, Mauricio Umansky, was cheating on her. By the end of the season, Vanderpump was on the outs with nearly everyone, including her former close friends, Glanville and Foster.

“Lisa feels genuinely sad by how the other women treated her last season, and so does her family," the source continued.

However, despite Vanderpump's delay in signing her season five contract, AllAboutTRH's source claims she will eventually return.

"Fans can expect to see her back on the next season. Filming is set to start pretty soon and potential new housewives have been testing on camera, but Lisa is having some playful fun knowing that the show wants her more than she wants it," the source explained.

In recent weeks, Vanderpump has been staying busy with her new restaurant, P.U.M.P., and with filming season three of her spinoff, Vanderpump Rules, which is set to premiere on Bravo this fall.
