Brandi Glanville has been talking about her closest friend on The Real Housewives of Beverly Hills, Kim Richards.

On last weeks episode, Lisa Rinna caught Kim Richards’ fire for expressing concern about her sobriety.

In fact, Richards said, “I have been sober for three years, and my friends and family have never seen me like that. You have gone around to everyone and talked … asking where I’ve gone to treatment, if I had a sponsor … you want to bring up my stuff, let’s talk about your home life.”

This hit a sensitive area for Rinna, and prompted her to eventually throw a glass of water on Richards, then break the glass on the table in an unusual fit of rage.

Now, it turns out that Brandi Glanville has also been talking about Kim Richards’ sobriety.

As Richards’ ally on the show, and a person that is not by any means rich in friends, Brandi Glanville is risking a serious tongue lashing from Richards, or even worse.

In a sneak peek for the next episode, it seems Kyle Richards, Kim’s sister, finds out that Brandi Glanville has been discussing Kim’s sobriety with other cast members.

All this discussion about Kim Richards’ sobriety started when she took a prescription pain killer before Eileen Davidson’s poker party that was not prescribed to her. As a result, Richards was noticeably out of it and slurring her words.

Brandi Glanville, as well as all of the other castmates began questioning whether or not Kim Richards was holding on to her sobriety. Even though Kim has said repeatedly that it was a simple mistake in medication, the other girls obviously found it troubling.

Will Brandi Glanville and Kim Richards be the next castmates to duke it out on the show after being friends for so long?

Time will tell.
