Kyle Richards and Kathy Hilton have reportedly reached a stalemate following an extremely troubling 12th season of The Real Housewives of Beverly Hills.
 According to a new report, Kyle and Kathy brought “a lot of tense energy” to the taping of the season 12 reunion last month after Lisa Rinna exposed details of Kathy’s alleged rant against Kyle on the show. And when it comes to their future, it’s hard to say if the sisters will ever be able to put their family feud behind them.
“They cannot reconcile, and it’s all so complicated because nobody’s backing down. Kyle has backed up her sister for years and no matter what she does, Kathy isn’t satisfied,” a source explained to PEOPLE on October 9. “What we’re watching is years of family trauma that hasn’t been dealt with in a family dynamic.”
While Kyle has been open about the ups and downs she’s faced with both Kathy and her other sister, Kim Richards, the insider said this time in their lives is particularly “complicated,” noting that Kathy’s daughters, Paris Hilton and Nicky Rothschild, have been forced to intervene for the “first time.”
“They all grew up together. Kyle acted as a spokesperson for the Hilton family for a long time. They always make up, but this is a little different because Kathy is front and center on camera,” the source revealed. “She hasn’t been forced to be vulnerable. Kathy and Kyle have spoken loosely via text only since the reunion.”
As RHOBH fans saw weeks ago, Lisa accused Kathy of going on a mean-spirited rant against Kyle during their cast trip in Aspen, during which she allegedly threatened to “destroy Kyle and her family if it’s the last thing” she ever does.
“We get in the sprinter van and Kathy starts screaming about everything, and she’d say things like, ‘I’m gonna take down NBC, Bravo, I will take down the show single-handedly. I will f-cking ruin you all!'” Lisa claimed. “What in the holy f-cking hell?”
“She takes her glasses off, she throws them on the ground, she’s jumping up and down, breaking her glasses, she’s pounding the walls and she’s screaming she ‘made’ Kyle,” she continued.
Then, during the finale episode, Kyle suggested that Lisa had come forward with the claims in an effort to distract from the legal issues of their castmate Erika Jayne, whose publicist she suggested was behind a series of press leaks.
“[I’m] forced to choose between my two friends and my sister,” Kyle shared in a confessional.
The Real Housewives of Beverly Hills season 12 reunion begins airing on Wednesday, October 12, at 8/7c on Bravo.
