Taylor Armstrong has been through so much – physical abuse
, the suicide of her estranged husband
and the public drama
of it all on The Real Housewives of Beverly Hills
, which played out on Monday's episode in a major way after she got into an intense fight with a friend of her costar Camille Grammer.
Now, she says, she wants to support someone else who is facing personal problems: her friend Kim Richards, who recently entered rehab.
"I adore Kim and I stand behind her," Armstrong told Andy Cohen Monday night on his 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 appeared on Cohen's show to talk about Monday's episode of Housewives
, all that she's been through and her new book
, Hiding from Reality: My Story of Love, Loss and Finding the Courage Within
