A source tells E! News that the reality star has been in a new treatment center for the past few days.

Richards entered rehab for the fourth time in April after being arrested at the Beverly Hills Hotel for intoxication. Days before her rehab stint, she stormed out of an interview with Dr. Phil after becoming increasingly uncomfortable with his questions about her arrest.

"I'm a very strong person and I have been sober," Richards told Dr. Phil. "I haven't been working a program. Living through a season on a show -- sometimes it's hard to just get through it. The fans are really hard on me."
