Kyle Richards And Sister Kim Feud During 'RHOBH' Party At Adrienne Maloof's Home

Kyle Richards and her sister Kim are reportedly on the outs.

According to a new report, there was "yelling, screaming, and plenty of tears" during the Real Housewives of Beverly Hills Season 5 finale party hosted by Adrienne Maloof after Kyle brought up allegations that Kim had relapsed. The drama went down at Maloof's home, where she was hosting a party to promote Never Hungover, a supplement company owned by her family.

"[Kim and Kyle Richards] had already been openly feuding over allegations that she had fallen off the wagon," a source revealed to Radar Online on October 29. "Kyle just doesn't believe that Kim is indeed sober. After the cast trip to Amsterdam, Kyle became even more convinced that Kim has suffered a setback in her battle with alcohol."

"But Kim absolutely maintains that she is still sober, and thinks the show is just exploiting her recovery," the source said. "So the sisters got into a huge fight at Adrienne's party. There was tons of yelling, screaming, and plenty of tears. It was so tacky to see these grown women behaving like this in public!"

Prior to the trip, a source claimed Kim wasn't feeling great about facing her demons overseas.

"Kim isn't thrilled about going. Being absolutely committed to her sobriety and going to a place that so many drugs are legal is bothersome for her," a source told Radar Online. "The main thing Kim isn't looking forward to is comments from the other ladies about her battle with alcohol and prescription drugs."

According to the Inquisitr, Kim's main issue throughout the season has been with one of the show's newest stars, Eileen Davidson, who was brought aboard The Real Housewives of Beverly Hills for Season 5, along with fellow soap star Lisa Rinna.

"Whenever Kim and Eileen film together, there is always a lot of eye rolling on the part of the soap star," a source revealed to Radar. "Eileen complains that Kim is a total airhead and doesn't understand why she is even on the show. In Eileen's opinion, Kim is a total bore, and just rides on her sister, [Kyle Richards]'s coattails."

Still, Kim hasn't engaged in Davidson's drama too much, reportedly because "she has been through it all and doesn't care what Eileen has to think or say about her. This is just a job for her and doesn't take it seriously at all."

Kyle Richards and the cast of The Real Housewives of Beverly Hills will return to Bravo later this year, with a premiere date for Season 5 coming in the "next couple of weeks," according to the Inquisitr.
