Kathy Hilton Responds To Kim Richards' Arrest

In the days prior, Hilton shared a few re-tweets from fans with her followers, which spoke of Richards' fragile emotional state.

As for Hilton's possible addition to The Real Housewives of Beverly Hills, which reportedly gave Richards the boot months ago, there have been several rumors.

“They’ve wanted to switch things up by trading the sisters for their much more famous sister,” a source close to the show told Radar Online a couple of months ago. “The one rub is they told Kathy not to say anything to them. So her sisters, like the rest of the cast, are in the dark about the new casting.”

“Execs initially wanted Kathy for the show years ago, but she passed. And she ended up recommending her sisters who were clamoring to do it,” the source explained.

However, according to Hilton, she's not joining the show.

The Real Houseiwves of Beverly Hills season six is expected to return to Bravo later this year.
