Real Housewives Kim

After watching Kim Richards’ bizarre behavior on The Real Housewives of Beverly Hills for months, we finally know the reason the reality TV star was acting strangely, and why she checked into rehab in early December. In People‘s exclusive sneak peek at the Housewives three-part reunion, Kim admits to Watch What Happens host Andy Cohen: “I’m an alcoholic.”

It’s not so much of a surprise to Housewives fans who watched Kim’s sister Kyle Richards accuse her of that very fact way back in season 1. But the scene from the reunion is shocking for a different reason: This is the most poised we’ve seen Kim since season 2 began. It’s been a long time since we’ve seen Kim calm, in control, and subdued — here’s hoping rehab helped the troubled reality star.

Now, if only the other Housewives cast members could be as poised. That’s right — it looks like we’re in for another doozy of a Housewives reunion, folks. We have Kyle referring to herself as the C-word, Lisa presumably talking about Brandi’s desire to sleep with her husband, and Kyle seemingly calling another cast member “Angry Spice.” (Probably because she never got her money back for this.) And, of course, we can expect plenty of talk about Russell Armstrong following his suicide: Cohen even asks Taylor if she ever considered whether or not he was murdered. Oy, PopWatchers, this is getting heavy — when can we just make fun of Slade again? (Oh, on Feb. 7? Thank you, Internet!) The Real Housewives of Beverly Hills reunion airs Jan. 30, Feb. 6, and Feb. 13. Check out People‘s exclusive clip here.

PopWatchers, are you ready to endure another Housewives reunion? Are you dreading the Russell discussion? Are you, like me, glad Brandi is there to lighten the mood? And, on another note, where’s Dana? (Boom mic?)
