New season, new feuds, new drama — that is the promise of the "Real Housewives of Beverly Hills" in the show's upcoming fifth season.

During Nicky Hilton's book launch in Beverly Hills on Oct. 21, RHOBH mainstay Kyle Richards told US Magazine, "It's going to be the most intense season we've ever had."

She said that the intensity of the show covers just about everything, including relationships, problems, and disagreements. 

Yolanda Foster, another cast member of the hit Bravo reality show, also believes that the program's fifth run will be a "very complicated season."  

"You know, I think it's going to be our best season yet," she said.  "I think a lot of things from last year... people are making up, new friendships, new people are coming into the group. I think it's going to be a great season."

As early as now, rumors are already circulating about the tiff between the newest cast member Lisa Rinna with other fellow RHOBH stars like Eileen Davidson and Kim Richards, and that her verbal arguments with the latter turned physical.

A source reportedly shared with RadarOnline, "All of a sudden out of nowhere, Lisa Rinna starts yelling and screaming at Kim... Lisa was furious with Kim about some perceived slight, and it quickly got physical."

The source also added that Rinna tried to push Richards, and made several ugly threats at her co-star. They even had to be separated by other people before the fight turned nasty.

Richards was also involved in another fight this season, since there were earlier reports that she had a little spat with her sister Kyle Richards after she accused Kim of slipping back to her alcoholic ways.  Kyle is allegedly not convinced that Kim is sober, especially after the cast returned from their trip to Amsterdam.

"The Real Housewives of Beverly Hills" will reportedly return to Bravo TV in November 2014.
