Regrets? Kyle Richards has a few.
"The events that transpired that evening were quite unfortunate and should never have occurred on or off camera," Kyle's statement reads. In the episode, the two sisters began bickering at Taylor Armstrong's birthday bash; things got vicious once Kyle joined Kim (who appeared to be under the influence) in a limo as Adrienne Maloof and a male pal looked on in horror. Kyle accused Kim of being an alcoholic; Kim bellowed mysteriously, "You stole my ****** house!""
Continues Kyle's statement: "There are a lot of elements to the story that viewers didn't see. This has been difficult for our entire family as we both said and did things that we regret. My sister and I love each other very much we want to move forward and put this behind us."
As noted at the end of the episode, former child actress Kim entered rehab for a week shortly after the disturbing incident -- and she and Kyle "didn't speak for a long time," Kyle writes in her blog.
"My heart was broken and I suffered an incredible amount of anxiety and panic attacks," she says of the estrangement. "Next to losing my mother, this was the most difficult time of my life."
What were they fighting about, anyway? "The tension between Kim and me was never about her not 'having my back' in New York," she says of a minor tiff earlier in the season.
"There is so much more to it than that. I didn't want to come out and say what it was that was really bothering me because this is a private family matter," says Kyle, whose eldest sister is Kathy Hilton, mom to Paris and Nicky.
The mom of four won't go into details about her sister's rehab stint, she says. "The details of what happened with Kim after that night, is her story to tell. I will not go into that here. I do want to say that I have learned a lot about my sister and myself during the taping of this show. I have been able to look at our relationship from an outsider’s point of view. I've realized that my pain and worrying about her comes off as anger. It was not helping Kim or our relationship. I love my sister and only want the best for her. Kim knows that."
