As season 5 of “The Real Housewives of Beverly Hills” draws to a close, rumors suggesting newcomers Lisa Rinna and Eileen Davidson are planning to exit the show have been swirling. Both Lisa and Eileen were friends of the Bravo cast before signing on as full-time “Housewives” – but are they rethinking their decision after finding themselves at the center of a conflict with veteran cast members Brandi Glanville and Kim Richards?

Lisa and Eileen's storylines picked up early in the season after Brandi began exhibiting strange behavior toward Eileen. Viewers will remember that Yolanda Foster, Brandi, Eileen and Lisa went out for lunch early on in the season. During their outing, Glanville, who is no stranger to controversy, tossed a glass of wine in Eileen's face without any explanation. Brandi later blamed her actions on having been to caught up in the moment.

Later in the season, tensions grew after a poker party, hosted by Eileen -- who is also a longtime soap opera actress -- turned ugly. Kim, who has allegedly been sober for quite some time, began behaving erratically, causing concern amongst the ladies – specifically Lisa. Unfortunately her concern was not well-received by Kim, who felt Lisa was invading her personal business. The two most recently fought in episode 16 when the cast traveled to Amsterdam. What began as a verbal disagreement quickly turned into a nasty fight during which Lisa nearly choked Kim.

Though Eileen and Lisa have found themselves in some nasty situations on "RHOBH," sources close to RumorFix say it is unlikely the "Housewives" newcomers will be leaving the hit Bravo series. The show has raked in high ratings this season. Perhaps, it has something to do with Eileen and Lisa's arrival. No matter the reason for the program's steady viewership, a quick trip to the girls' social media pages proves the duo have attracted quite the  fan base.

Neither Lisa nor Eileen has addressed the cast rumors and, as Lisa's tweeted many times before, “It's only true when it comes from my lips.”

The drama will continue on next week's episode of “RHOBH” as the housewives' volatile Amsterdam vacation comes to an end. New episodes of the series air on Bravo Tuesdays at 9 p.m. EDT.
