Though it isn't clear what affliction Richards, 47, is seeking treatment for, her use of alcohol has become a point of concern on the series. During the "Beverly Hills" season finale last January, Richards' sister, Kyle Richards, lashed out at her sister, accusing her of being an alcoholic. More recently, in an episode that aired in October, Richards' new castmate, Brandi Glanville, accused Richards of being "wasted out of her f—ing mind," an accusation that Richards denied at the time.
