Real Housewife Kim Richards has Taylor Armstrong's support

It was announced Monday (Dec. 5) that "Real Housewives of Beverly Hills" star Kim Richards (above, left) has entered rehab at an undisclosed treatment facility. Her co-star Taylor Armstrong (above, right) has pledged her support to Richards through this trying time.

"I adore Kim and I stand behind her," says Armstrong, on Andy Cohen's Bravo talk show "Watch What Happens: Live." "And if there's anything I can do to support her [I will], but if she's getting healthy, what more could we ask?"

Armstrong has been through the emotional wringer herself, as her estranged husband Russell Armstrong was abusive towards her and then back in August, Russell took his own life. All of the drama has of course played out publicly in the media and on the "Real Housewives" series.

On Andy's show, Armstrong was also talking about her new book, "Hiding from Reality: My Story of Love, Loss and Finding the Courage Within," which is due out Feb. 7, 2012.
