Just a few weeks after "The Real Housewives of Beverly Hills" cast member Kim Richards admitted herself to a rehab treatment facility to address her alcohol problems, a new report claims that the troubled reality show star quietly left before the recommended treatment period lapsed.

RadarOnline spotted an Instagram post of Richards' half sister Kathy Hilton taken last week. In the photo, Paris and Nicky Hilton's mother posed with the troubled "RHOBH" star and her niece Brooke Brinson during the latter's bridal shower.

Hilton captioned the picture, saying: "With my beautiful sister and niece @kimrichards11 @brookewiederhorn so happy for you and Thayer! Wish you both a long life together xoxo Aunt K."

The eldest among the Richards' siblings, including "The Real Housewives of Beverly Hills" co-star Kyle Richards, expressed her support for the problematic Bravo-lebrity.

"I'm very proud of her, she decided on her own to go. I just want to do the right thing, and I want to be the strongest I can be," the hotel heiress and philanthropist stated during the recently concluded Ovarian Cancer Research Fund's 2nd Annual Super in Los Angeles.

Richards was arrested last month for public intoxication, and she was slapped with multiple charges including resisting arrest and battery on an officer.

However, reports claim that Richards' attendance in her daughter's bridal shower was not the first time that she was seen in public after she checked herself in the rehab. According to reports, she was seen shopping at the Malibu Country Mart around two weeks before Brooke's bridal shower.

Kay Rozario, Richards' former friend who recently won a court case that she filed against the reality star after the latter's viscious pit bull Kingsley attacked her, also claimed that she is out of rehab already.

No word from Richards' camp had been heard regarding the rumors, but Bravo execs allegedly told her that she needs to complete her entire rehab stay in order to remain in "The Real Housewives of Beverly Hills."
