'RHOBH' Kyle Richards Accuses Sister Kim Richards Of Drinking Again! Is This The End Of Kim On 'Real Housewives Of Beverly Hills'?

Real Housewives of Beverly Hills star Kim Richards doesn't only have to deal with co-star Eileen Davidson's accusations of her drinking again, but now her sister Kyle Richards is getting in on the action.

As MStars News reported, Days of Our Lives star Eileen accused Kim of falling off the wagon on their recent trip to Amsterdam, Netherlands.

"No one saw Kim drink or take any pills, but she did slightly slur her words during one of the initial outings on the trip," according to Radar Online. "Eileen was trying to stir things up behind the scenes, along with Yolanda [Foster], questioning Kim's sobriety."

This got Kim's sister worried, so she took Kim on a trip to Palm Desert to try and get to the bottom of the allegations.

"Producers of RHOBH are finally getting the drama they wanted as filming winds down," a source told Radar. "Kyle doesn't want to believe that Kim has fallen off the wagon, but needed to spend time with her to talk about it. Naturally, cameras from the show had to be there to document it."

The reality star left the trip with even more doubts about her sister's sobriety.

"Let's just say after the weekend was over, Kyle had even more concerns about Kim's sobriety," the source said. "There were tons of tears, and Kim got very defensive when confronted by Kyle about accusations she had indeed suffered a setback in her recovery."

This could be the last season for Kim if she becomes even more upset about the claims against her from the other girls, including her own sister.

"[Kim] wants to finish filming for the season and stop being made to be the subject of yet another stupid storyline on the show," the source continued. "It's old, tired and boring. She is completely over it."
