Kyle Richards settles feud with estranged sister Kathy Hilton after 'meaningful' apology

Kyle Richards, a Real Housewives of Beverly Hills cast member, and her sister Kathy Hilton have patched up their differences in the same spot where they first clashed.

At their niece Whitney Davis' wedding over the weekend, Hilton apologised to Richards in front of a camera at the upscale Western wear retailer Kemo Sabe in Aspen, Colorado.

"I'm sorry. It wasn't your fault. It was not your fault," the 64-year-old mother to Paris and Nicky Hilton said in an Instagram Story shared by Kyle's eldest daughter, Farrah Aldjufrie.

Kyle looks stunned and yells, "Get the video! Get the video!"

"It's not your fault. It was not your fault," Kathy explains. "I was just being sad."

When Kyle arranges a trip to the Aspen hat shop on RHOBH season 12, Kathy is delighted to discover that the store's bar was pouring her tequila brand, Casa del Sol. Even yet, Lisa Rinna's request for a shot of Kendall Jenner's 818 tequila made her angry.

Kathy interpreted Lisa's slight as a personal jab and became angry that her sister didn't step in. Eventually, Kathy walked away, calling herself "[expletive] pissed off."

The ladies went to a club later in the evening where Kathy became irate once more with the females and ultimately left with Lisa.

"We get in the sprinter van and Kathy starts screaming about everything and she's saying things like, 'I'm going to take down NBC, Bravo. I will take down the show singlehandedly. I will [expletive] ruin you all,'" Lisa says in a confessional.
