Despite her ongoing feud with Kim Richards, Lisa Rinna remains close to Kim's sisters, Kyle Richards and Kathy Hilton.

In addition to a Thursday morning tweet about a recent conversation with Kyle, Lisa was recently mentioned in a report, which revealed she and Kathy, the Richards sisters' older half-sister, were still friends.

Before The Real Housewives of Beverly Hills reunion, as reported by AllAboutTRH, Kathy tweeted, “I will be watching The Housewives of Beverly Hills 2night 2 see who is naughty & who is nice. Part 2 of the reunion! Can”t wait... I hope everyone behaves 2nite!!!”

In response, Lisa promised she and her co-stars would be “on our best behavior.”

Although fans may have assumed Kathy would not be on good terms with Lisa due to her often harsh comments about Kim and her struggles with sobriety, Kathy recently told her fans and followers that Lisa was a “good girl” -- and that they “have been friends four yrs.”

Kathy also confirmed the ladies' on-screen drama was now water under the bridge.

“She is new & she has said she is sorry," Kathy explained.

In other tweets, Kathy denied reumors of her possibly replacing Kyle on The Real Housewives of Beverly Hills, telling fans, “No, I love my sister,” and in regard to sister Kim, she added, “Kim has been around this business longer than anyone of these ladies. Trust me she is stronger than u realize."

After watching the reunion unfold, Kathy had some pretty strong feelings towards some of the women, although she didn't say who.

“Don”t u c the long jealous faces of some of the woman on the sofa when @andy gives attention or asks a question?” Kathy tweeted. “And the one always interjecting just to get her mug on camera & and answer a question not directed two her. Acting all concerned.”

"They get on a subject & beat 2 death! It’s call deflecting,” she continued. “Most of the women want to stay far away from their own lives.”

Part three of The Real Housewives of Beverly Hills season six reunion airs Tuesday night at 9 p.m. on Bravo. Check out a sneak peek at the upcoming episode below.
