Pictures: Stars in rehab The website did not say what Richards is seeking treatment for. Last year, she and sister Kyle Richards got into an explosive argument that was shown on the season finale of “Real Housewives,” during which Kyle called Kim an alcoholic. At the end of that episode, viewers were told that “Kim’s family checked her into rehab … A week later, she checked herself out. She is taking her life one day at a time.” This season, People magazine notes, new co-star Brandi Glanville accused Richards of being “wasted out of her f—–g mind” during a recent episode. Richards denied it and the two got into a shouting match. In another episode, it was revealed that she was taking anti-anxiety and anti-depression medications.
