"Real Housewives of Beverly Hills" star Kim Richards has entered rehab, "Entertainment Tonight" reported Monday.
The former child actress has checked into an undisclosed center and is believed to be seeking treatment for alcohol issues, sources told the showbiz television show.
Her drinking problem has been chronicled on the Bravo reality show, on which she appears with her sister, Kyle Richards.
On the show's first season finale, a visibly drunk Kim Richards got into a shouting match with her sister, who yelled, "You are an alcoholic! Yeah, that's right. I've said it now and everybody knows."
After the siblings' heated exchange, Kim Richards' family checked her into rehab, but she checked herself out after one week of treatment.
The 47-year-old has four children from three different relationships.
Her half-sister is Kathy Hilton, mother of celebutantes Paris and Nicky Hilton.
