Kyle Richards has been a fan-favorite on "The Real Housewives of Beverly Hills" for her fashion sense and her relationship with her daughters, particularly her youngest one, Portia. While her sister, Kim Richards, is not a regular on the current season because she has chosen to focus on her health and well-being, Kyle is still a mainstay on the Bravo series. But earlier this week, her brother-in-law said that the 46-year-old will be leaving the show very soon.

TMZ caught up with Kyle's brother-in-law, Rick Hilton, at LAX on Monday, Dec. 28, and the businessman told the media outlet that Kyle was upset with Bravo for airing her family's feud so she decided to quit the show.

"Kyle said that she was gonna give notice to quit the show because of what they made her [do], for the information [that was given] on the show," said Hilton. "That was nice of her to do."

When asked what would happen if Kyle changes her mind about quitting, Hilton replied, "She's told us she's already given them notice, so it already happened."

Two days after Hilton's interview with TMZ, a source told Radar Online that Kyle denied her brother-in-law's claims, saying that it was his latest move in the ongoing family feud.

"Kyle was absolutely stunned," said the insider.

The source added that there has been so much drama going on between Kyle and her sister Kathy Hilton since Kathy's daughter Nicky's wedding last summer. It was revealed on an episode of the Bravo show that Kyle was disinvited at the last minute.

The source said that while Kyle told her sister that she asked the network to cut any further mention of the wedding, there was never any talk about her quitting the show.

The insider said that Kyle thinks that Rick is trying to "publicly pressure her into leaving" the show.

"If she refuses to do so, it will make her look bad," said the source.
