'Real Housewives of Beverly Hills' star Kim Richards has once again entered rehab, according to ETOnline.
Kim, who has become known for her erratic behavior on the Bravo series, has reportedly entered an undisclosed treatment center.
Following the Season 1 finale in January, which featured an argument with her sister Kyle, Kim reportedly checked into rehab, but left a week later.
"You are a liar ... [and] you are an alcoholic! Yeah, that's right. I've said it now and everybody knows," Kyle Richards said in the Season 1 finale.
The two sisters had been at odds until filming began for Season 2. However, they seemed to unite when Brandi Glanville made references to Kim being intoxicated. Watch video of that incident below.
