"The Real Housewives of Beverly Hills" promises more drama this season. With the addition of new cast members, new catfights and new friendships are sure to be formed.

As for mainstay Lisa Vanderpump, she might have found her new BFF in new cast member Lisa Rinna.

As Reality Tea claimed, Vanderpump explained that if it wasn't for Rinna, she would have really decided to exit the show this season.

"Of course I show reticence at the beginning of this season with regard to engaging most of the women. It had been a devastating experience, and I was unsure of what to expect. I knew they had all had contact with each other over the many months that had passed, and I had had none until very recently with Kyle. When it was mentioned to me that maybe Lisa R. was joining, I felt slightly differently. You will enjoy getting to know her. Her energy is boundless and positivity infectious," Vanderpump shared.

Previous "The Real Housewives of Beverly Hills" reports talked about Lisa Vanderpump leaving the reality show this season. 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.
