It's a chaotic season on the set of the Bravo-aired reality TV show "Real Housewives of Beverly Hills."

RadarOnline reports with higher-ups concentrating on meeting deadlines for having all next season's contracts signed, several of the show's biggest stars have joined forces to demand hefty pay raises.

All this comes on the heels of show executives recently deciding to part ways with cast member Kim Richards after yet another drunken public meltdown, this time at her daughter's Cabo San Lucas, Mexico wedding several weeks ago. Richards is now reported to be a in a 90-day inpatient rehabilitation program in Malibu.

Following their announcement to fire Kim, her sister, Kyle, reportedly begged and pleaded to keep her position, but right now even she may be on the verge of leaving on her own to work with TV Land on a show about her famous upbringing.

"Bravo is not 100 percent sure if Kyle is going to return right now and with the loss of Kim and potentially another housewife, it could mean the end of the show," said a source. "No one knows how well RHOBH's audience will take to two or more housewives leaving and they think it could spell disaster."

They may soon faced the network's answer. On Thursday, came news that Brandi Glanville won't be returning to the show. According to People, the 42-year-old Glanville has feuded with every other cast member and her clashes with Kyle Richards have become legendary.

A four-year veteran of the show, the magazine reported she could still appear in some episodes as a special guest, similar to the way former cast mates Adrienne Maloof and Camille Grammer have done.

Previously, Yolanda Foster announced she will not be returning next season as she battles Lyme disease.
