Kathy Hilton is already setting the tone for season 15 of “The Real Housewives of Beverly Hills,” and according to her, fans should prepare themselves — because things get “brutal.” The Bravo icon hosted her annual holiday Pajama Party this week, and between the matching pajamas, celebrity guests and Bel-Air holiday glow, Kathy still found time to spill on what’s coming when the show returns December 4. And yes, she swears she’s not the one causing chaos this time.

Kathy Hilton Says RHOBH Season 15 Is ‘Brutal,’ But She’s Not Involved in the Drama

Speaking to Variety at the event, Kathy said the new season goes hard — just not because of her.

“It’s pretty brutal,” she admitted. “There’s no Kathy Hilton drama. I’m not really dramatic. All that drama makes me really sad. They’re all just very comfortable in saying whatever they want, and that’s what makes it brutal.”

The Bel-Air bash, cohosted with her daughter Nicky Hilton, was full of familiar faces: Denise Richards, Sutton Stracke, Crystal Kung Minkoff, Faye Resnick, and Heather Dubrow all showed up in support. But even in pajama-party mode, the cast couldn’t resist reacting to the newly released trailer.

“I had a couple of phone calls today from some of the girls after they saw the trailer,” Kathy revealed. “Some of them were like, ‘I can’t believe so-and-so did this.’”

And then there’s newbie Rachel Zoe — a casting surprise that immediately got the fandom buzzing. According to Kathy, the stylist-slash-fashion legend didn’t rock the boat.

“She came in and fit right in,” Kathy said, adding, “I don’t think she caused any drama.”

Nicky, who appears in the season 15 finale, chimed in with her own tease, calling the finale “very dramatic.” Kathy didn’t miss the chance to drive it home: “It was bru-tal!”

With that kind of warning from someone who has lived through a few RHOBH wars herself, fans should buckle up. “The Real Housewives of Beverly Hills” season 15 premieres Thursday, December 4, at 8/7c on Bravo.
