The sixth season of "The Real Housewives of Beverly Hills" ended with very little conflict and drama but that does not mean the upcoming season 7 won't see a shake-up in its cast. As stated in a report from Ecumenical News, some of the cast members may not be coming back for the show to focus primarily on their solo career.

As previously reported, Lisa Vanderpump may no longer be returning for season 7 as the reality show star is going to focus on her solo series and is still busy running three restaurant chains and a pet clothing line. However, this does not mean Vanderpump is permanently leaving as she may still appear as a recurring guest star.

Ecumenical News also points out that Kyle Richards, who has remained as one of the main stars since season 1 alongside Vanderpump, may also be sitting out season 7. The report points out that her sister Kim did not even appear until the latter half of season 6 and that fans are no longer interested in their story.

If both Vanderpump and Richards leave then season 7 will no longer have any cast member from the original lineup. Camille Grammer quit the series following season 2 and both Adrienne Maloof and Taylor Armstrong left after season 3, coming back only as guests. 

Brandi Glanville, who was credited as a main cast member for seasons 3 to 5 and a guest star for season 6, is also rumored to quit. It is stated that her guest appearance in season 6 may be an indication she will return for season 7 but it is also explained the reality show star may instead prioritize her own show. 

Several stars are confirmed to return, however. Responding on Twitter, series creator Andy Cohen confirmed that he would not be removing Eileen Davidson and Yolanda Hadid anytime soon. Both have been credited as main stars for several past seasons.
