Kim Richards

Real Housewives of Beverly Hills star Kim Richards has left rehab, People reports.

Richards, 47, checked in last month for alcohol abuse and other "serious issues." She previously sought treatment after the taping of the Season 1 finale, in which she got into a heated argument with her sister and castmate, Kyle Richards, who called her an alcoholic.

Earlier this season, new cast member Brandi Glanville accused Richards of using drugs during a game night with the ladies.

The cast taped a reunion show last week, but it is unclear if Richards participated.

"It was high drama, lots of emotion, and some fun and laughs too," Andy Cohen wrote on his blog. "All the women deserve a pat on the back. High highs and low lows."
