It’s been an emotional season for “The Real Housewives of Beverly Hills” star Kim Richards.

She’s been in and out of rehab and now she is finally ready to come clean about her struggles.

Kim, who was in rehab at the time, did not make an appearance at the show’s reunion show, but she did later sit down with Bravo’s Andy Cohen to talk about the show and her treatment.

In the interview Kim will explain the reasons behind her odd and erratic behavior on the show.

When asked why she went to rehab Kim responded, “I’m an alcoholic.”

This comes as no surprise her cast mates on the show who have had to deal with Kim’s antics throughout the season.

“I think we were all aware that something was off, but we didn’t know quite what it was. It was very difficult to try and ascertain,” Lisa Vanderpump admitted when asked if she knew Kim was struggling. “I think she wouldn’t have gone without really needing to be there. She obviously has to sort something out.”

Adrienne Maloof added, “It takes a lot of courage to do what she has done. It’s a step in the right direction.”
