'RHOBH' Lisa Rinna Claims Kathy Hilton Promised To 'Destroy' Kyle Richards

Reality star Lisa Rinna recently claimed that fellow cast mate Kathy Hilton promised to ruin her sister after a ladies' night gone wrong. The recent incident is only a bit of the drama that went on in Aspens during the cast's ladies' trip.

Hilton initially joined the cast of "Real Housewives of Beverly Hills" in season 11 as a "friend" of Kyle Richards. According to Richards, despite their ongoing rifts on tv, she was the one that pushed for Hilton's inclusion in the television series.

Rinna detailed the two sister's recent fight, revealing that Hilton said she was going to destroy the show, Bravo, NBC, and the rest of the cast members. The 63-year-old also allegedly said she would take down her sister and her family "if it's the last thing I ever do."

In a preview footage of the Wednesday episode of "Real Housewives Of Beverly Hills" (via Page Six), cast member Rinna revealed that she heard Hilton promise to "ruin" her sister, Richards, and the reality star's family. The duo previously had a heated argument while they were in Aspen, Colorado.

"We get in the sprinter van, and Kathy starts screaming about everything," the 59-year-old recalled. "And she's saying things like, 'I'm going to take down NBC, Bravo … I will take down this show single-handedly. I will f–king ruin you all.' What in the holy f–king hell?"

According to Rinna, the issue escalated further when she returned to Richards' house with Hilton. The 63-year-old reportedly threw her glasses on the ground and broke them. The Rinna Beauty founder added, "She said, 'I will destroy Kyle and her family if it's the last thing I ever do.'"

According to the rest of the cast members present during the chaotic night in Aspen, Hilton was mostly furious at Richards. During a confessional, Richard revealed that most of her sister's "screaming and raging," as described by the cast members, began after she refused to leave the club with her.

"Kathy was saying that she was pissed off and that I had to leave the club right now," the 53-year-old recalled. "I was very confused because I didn't even know what happened. So I said, 'no, I'm not doing that we just got here, Kathy.'"

Another "RHOBH" star, Sutton Stracke, claimed that Hilton's behavior that night was tied to most of the cast ignoring her when she asked to do the conga line. "Kathy was just a little off. She kept asking everyone to do the conga line, and I don't think anybody wanted to do it," the reality star recalled. "And the next thing I know, she's in my face saying that she wanted to go home and if 'you don't go home with me, you're not my friend.'"

According to Richards, she started getting into serious fights with her sister, Hilton, right from when they were kids. 

While talking to Page Six in May, Richards revealed that she had always had a "complicated and complex" feud with her sister, which became even more pronounced because they were on TV together. She said, "It's so complicated and complex. All I can say is, we're family, and we're going to have these moments."

"I feel like my sisters and I; we have arguments, we make up, we're blood. I don't know if everyone is like that. The fact that we're on television complicates things," the 53-year-old continued.

Earlier on, Richards got some heat from fans and her niece, Paris Hilton, who called her "unkind" for mocking her sister during the Aspen ladies' trip. The 63-year-old reportedly tried to promote a tequila brand that she and her family invested in; however, she was ultimately shut down by the group.

At the time, Hilton brought the women together and asked that everyone try a shot of the Casa Del Sol drunk. She was ignored by most of them, including Richards, who made a buzzing noise and then carried on her conversation with Rinna and Erika Jayne.

Several fans criticized the 53-year-old's behavior, and "RHOBH" alum Denise Richards took to Twitter to talk about it. She wrote, "I felt bad for her you could see her feelings were genuinely hurt & the preview with Rinna going out of her way to take a dig."
