Mean Girls At War! 'RHOBH' Cast Gangs Up On Newcomer Eden Sassoon

The upcoming season of Real Housewives of Beverly Hills is going to be the nastiest season ever! As fans of Bravo's hit reality series know, last season's mean girl mayhem was too much for both Yolanda Foster and Kathryn Edwards to handle. But now that the two blonde beauties are gone from the show, RadarOnline.com has exclusively learned that RHOBH's vicious veteran vixens have found themselves a new target: heiress to late hair and beauty icon Vidal Sassoon's empire, Eden Sassoon! Click through seven Beverly Hills brawling photos to find out if Sassoon is going to be able to take the housewives' heat!

RHOBH fans and cast members alike have been desperate to know who will replace the second spot left open by Lyme disease victim Foster, 52, and soap queen Edwards, 52! And when Sassoon announced that she is taking one of those spots, a source told RadarOnline.com that "several Housewives lost it!"

"Lisa Vanderpump, Lisa Rinna and Kyle Richards really do not like Eden at all," said the source, adding, "Lisa Rinna, especially, does not get along with Eden." During a recent interview, Rinna, 53, made her opinion about Sassoon clear when she said, "I WAS a big fan of her dad's!"

"Some of them say she acts like the first big fortune heiress to ever be on RHOBH," said the source.

As previously reported, Kyle Richards, 47 — whose rehabbed sister, Kim Richards, 47, is rumored to be returning for the upcoming season — trashed Sassoon during a recent photo shoot.
