Real Housewives of Beverly Hills star Kim Richards admitted that she is an alcoholic, a preview of the show released Thursday revealed. Richards entered rehab in December, but this is the first time she has admitted publicly to the disease. She didn’t participate in the initial filming because she was seeking treatment for alcohol abuse. Her sister, Kyle Richards, was confronted about alcoholism in the first season of the show. The special, titled Watch What Happens, also features other heavy issues, such as Taylor Armstrong discussing her husband Russell’s suicide.
