'The Real Housewives Of Beverly Hills' Lisa Vanderpump Leaves Reality Show To Focus On Her Business? New Season Airs November 18 With New Drama!

"The Real Housewives of Beverly Hills" returns on November 18 with new drama and new cast members.

Former "Days of Our Lives" stars Eileen Davidson and Lisa Rinna are set to join the housewives this season.

Meanwhile, the drama continues if not escalates, as a recent report claims that the housewives are ganging up on fellow cast member Kim Richards.  The reason? They think she has a drinking or drug problem.

An insider told Radar Online, "Things got extremely tense very quickly in Amsterdam because the ladies, led by newcomer Eileen Davidson, believed that Kim was under the influence of something."

"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," the source added.

If fans can remember, this wasn't the first time Kim was suspected of being under the influence. In season 3, Kim acted weird and slurred her speech during the cast's trip to Paris.

Another "The Real Housewives of Beverly Hills" report talks about Lisa Vanderpump's rumored departure from the reality show.  In Vanderpump's interview with Inquistir, she revealed that the previous season was difficult, but denied speculations that she will not be coming back.

"There was a moment where I thought I just can never go back to that because it was so difficult.

"But...I'm awfully glad I did because I do think this is going to be our best season yet!"

However in a recent interview with Us, Lisa confessed that she is really not sure whether she would be returning to the show after this season. 

"I don't know. I just always think... if this is how they document my life, it's fantastic, really," she said.

Whether Lisa chooses to leave the show or not, the fab entrepreneur still have a lot of things to be busy about.  The Beverly Hills housewife will be launching her own home décor line soon.

I've always loved kind of creating ambiance and that's what I've done," she said. "It's important to me to create this kind of whole feeling, where you feel so welcome and that was always my aim at home. It was a natural extension for me to do a tabletop line."
