But while it was Glanville who first started feuding with Vanderpump, sources close to the situation exclusively tell RadarOnline.com that all the women of the Real Housewives of Beverly Hills have come to realize what kind of person the Villa Blanca owner is after catching her in lies.
"Lisa needed someone to instigate things, to out her and show her true colors, and that person was Brandi," the insider told Radar.
"All the women on the show have come to realize how conniving and manipulative Lisa is. Brandi was the only one with the balls to actually call her out and do something about it."
Furthermore, the source tells Radar that castmates are siding with Glanville despite any prior grievances they've had with her.
“It involves everyone in the cast…there is so much more to it. But let’s just say I’ve grown closer to Brandi. It’s no secret that Lisa and I have had our issues in the past.”
And the source thinks the feud will be a major plot in the upcoming season of theReal Housewives of Beverly Hills.
"Brandi was tired of being Lisa's b*tch. She has no problem being a b*tch in general, but just not anyone else's," the source added.
"A lot of it will come out on the show and the world will learn what the girls on the Housewives already know about Lisa."
