Lisa Rinna and Erika Girardi are reportedly at war with one another amid production on the upcoming eighth season of "The Real Housewives Of Beverly Hills." On October 17, Champagne and Shade revealed that Rinna had allegedly prompted an argument with the singer in the middle of the street during a cast trip to Berlin, Germany, where both ladies have been sharing tons of photos, along with their co-stars, including Lisa Vanderpump, Kyle Richards, Teddi Jo Mellencamp, and Dorit Kemsley.

As Champagne and Shade explained, there are also two part-time cast members included in "The Real Housewives of Beverly Hills" season eight but those women weren't seen on the trip.

As for who those women are, the part-time roles could belong to Camille Grammer and Adrienne Maloof, both of whom were seen alongside their fellow cast members in Las Vegas months ago.

Kyle Richards attempted to smooth things over between Lisa Rinna and Erika Girardi

According to All About the Tea, Kyle Richards attempted to intervene between Lisa Rinna and Erika Girardi, who is also known as Erika Jayne, after things continued to escalate. Although it is not yet known what the women's argument was about, the outlet claimed Rinna had been drinking, which certainly didn't help with their interaction.

All About the Tea shared a number of images from the women's night out and in the photos, Rinna was seen screaming at her co-star.

Meanwhile, Vanderpump was seen behind the women, seemingly doing her best to steer clear of the drama between them.

Lisa Rinna joined 'RHOBH' during its fifth season

Lisa Rinna and Eileen Davidson were brought to "The Real Housewives of Beverly Hills" in 2014 for season five and continued to film full-time until earlier this year, when Davidson suddenly announced that she would no longer be participating in the production.

While Davidson will not be seen on the show's upcoming eighth season, she and Rinna appear to have stayed in touch and, ironically, Davidson appears to have remained close with Rinna's on-screen nemesis, Girardi, as well.

To see more of Lisa Rinna and her co-stars, including Lisa Vanderpump, Kyle Richards, Erika Girardi, Dorit Kemsley, Teddi Jo Mellencamp, Camille Grammer, and Adrienne Maloof, tune into the upcoming eighth season of Bravo TV's "The Real Housewives of Beverly Hills." The show's latest installment will begin airing sometime later this year.
