There’s more drama for the Real Housewives of Beverly Hills.

Real Housewives’ Kim Richards has checked into an undisclosed rehab treatment center, reports Us Weekly.

Former Disney child star Richards, 47, exposed her problem with alcohol in the shocking first season finale of the Bravo hit – in which she appeared intoxicated during a brutal fight with younger sister Kyle Richards.

Sister Kyle, 42, called her an “alcoholic” during the ugly brawl, and Kim briefly entered rehab at that time (mid-2010) for treatment, although she declined to discuss her addiction problems on camera or with the press.

Kim’s behavior on the second season of the show (currently running) remained erratic. At one infamous game night hosted by new castmate Dana Wilkey, Brandi Glanville accused Kim – who made frequent bathroom breaks and slurred her speech – of being high on crystal meth.

Richards is a former child actress who starred in “Nanny and the Professor” and “Escape to Witch Mountain.” She is the younger sister of Kathy Hilton who is Paris Hilton’s mother.

Her “Real Housewives of Beverly Hills” co-star Adrienne Maloof reportedly told reporters that Richards’ move to go to rehab was “a step in the right direction.”

The second season of “The Real Housewives of Beverly Hills” made headlines shortly before its premiere in September when Russell Armstrong, husband of cast member Taylor Armstrong, committed suicide in August.

Russell Armstrong was found hanging in a bedroom in a Hollywood Hills home where he had been staying after separating from his wife, who filed for divorce in mid-July.

Armstrong was laid to rest nine days after his body was found.
