( EW.com ) -- 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 . `` The Real Housewives of Beverly Hills '' reunion airs January 30 , February 6 , and February 13 .
