Kim Richards is finally getting the help many believe she so desperately needs.

Several insiders confirm to Us Weekly that the Real Housewives of Beverly Hills star, 47, has checked into an undisclosed rehab facility; Entertainment Tonight first reported the news of Kim's treatment.

Though Bravo declined to comment, Kim's costar Adrienne Maloof told Us Weekly at Macy's in Sherman Oaks, California: "I wish her well. It's a step in the right direction."

Maloof isn't the only one rooting for the former child star, who briefly sought treatment in mid-2010 after her sister Kyle, 42, called her an "alcoholic" on national television.

"Kyle is doing okay. Even though Kathy [Hilton] is not on the show, I know that they are close," a source tells Us of the tight-knit sisters. "It must be very difficult for Kyle and Kathy and their families."

Adds a second insider: "The only way Kim is going to be able to move on and enjoy her life is to free herself of these demons."

During season two of the Bravo hit, Kim's erratic behavior caused costar Brandi Glanville to accuse of her being "wasted out of her f-cking mind" during game night at Dana Wilkey's house.

Maloof's husband, Dr. Paul Nassif, attributed Kim's slurred speech to a bad combination of prescription pills: Lexapro (anti-anxiety), Trazadone (antidepressant) and Topamax (an anti-seizure medication that can also be used to treat alcoholism).
