It’s War — Already! New Cast ‘RHOBH’ Star Eileen Davidson Feuding With Kim Richards — Their Nasty Fights Exposed

Soap sudser queen and reality star, Eileen Davidson is new to the Real Housewives of Beverly Hills, but she already knows how to make a scene: RadarOnline.com has learned that she’s been openly mocking Paris Hilton's aunt, Kim Richards, during filming of the reality show, and while some cast members don’t like it, producers think it will be ratings gold!

Newcomer Davidson "didn't make any effort to try to get to know Kim at all,” an insider tells RadarOnline.com. "Eileen can come off as very snobbish and aloof.”

"Whenever Kim and Eileen film together, there is always a lot of eye rolling on the part of the soap star,” the source reveals. "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's coattails.”

The veteran Days of Our Lives and The Young & The Restless star “has indeed signed on to join the cast for the Real Housewives of Beverly Hills,” the source confirms. "She was only working on a limited basis for DOOL and Y&R. Eileen has a huge fan following, and will be paid for $750,000, which is a record for a new cast member.”

In addition, notes the source, “There's a very interesting dynamic between Eileen and fellow cast member and soap sudser, Lisa Rinna. Everyone will be extremely surprised by their relationship."

But for Davidson’s frenemy Kim, the "drama is nothing new,” the source explains. “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."

Filming for the upcoming season is currently underway, and the ladies are getting ready to take their annual trip to an exotic locale.
