According to sources Kim was “doing well” in treatment but as Nicky’s wedding approached and she was left out of family festivities, including bridal showers and other events, she grew increasingly upset.

According to TMZ the reality star was reportedly not getting along with staff, including doctors, so packed her bags and left the Malibu center in the middle of the night over the weekend. After opening up about her struggles to Dr. Phil in an exclusive interview, the Bravo star went to rehab.

Former “Real Housewives of Beverly Hill” star Kim Richards is already out of rehab, TMZ reports. She briefly left the facility in May to attend the wedding of her and Brinson’s 29-year-old daughter Brooke to Fatburger heir Thayer Wiederhorn in Cabo San Lucas, Mexico.

It looks like Kim Richards is done with rehab once again and has skipped out.

She checked herself back into a different rehab facility when she fell off the wagon at Brooke’s nuptials.

Amid reports last month that Kim has been axed from RHOBH after five years, speculation is growing that Bravo producers are trying to woo her sister Kathy to appear as her replacement. Luckily, she eventually returned to the States – and to rehab. As the Inquisitr previously reported, Brinson applauded Kim Richards for her determination in an emotional Instagram post last week.

“[Kim Richards] has been telling her friends in rehab that she was not fired from Real Housewives at all”.

Richards originally check into the rehabilitation program for three months, but now says she is done for good.

[Kim Richards] can paint it however she wants.

No word on where Kim now is – she moved out of her LA home a couple weeks ago and is said to be in limbo over where she would live following treatment, which she obviously exited early…

Meanwhile, latest “The Real Housewives of Beverly Hills” spoilers and cast updates also teased that Angie Simpson, mother of Cody Simpson, could be asked to join the show.
