Brandi Glanville is still not okay with Lisa Vanderpump and Scheana Marie's friendship.

Is Brandi Glanville Picking Fights Over Twitter?

Because of Scheana Marie's three-year affair with her ex-husband, Eddie Cibrian, Glanville has never been on board with her Real Housewives of Beverly Hills costar, Lisa Vanderpump, being her friend. Even now that Glanville and Vanderpump aren't close, the ex-wife of the cheating actor is frustrated by the pair's friendship.

“I loved Todd and Lisa V. They were very important to me,” Glanville wrote in her Bravo blog on Thursday, recalling the early moments of her friendship with Vanderpump. "Lisa asked me to have a sit down with the woman who was my husband’s mistress for three years, throughout my entire second pregnancy!"

Are Leann Rimes and Brandi Glanville On Good Terms Now?

According to Glanville, Scheana Marie announced her affair with Cibrian, who was also cheating on Glanville with country star LeAnn Rimes, on national TV, "not to me, not to confess, not to apologize, but on Access Hollywood, for fame." At the time, Scheana Marie claimed she had no idea Cibrian was still married.

"So, with great reluctance for my new 'good' friend, Lisa V., I threw myself on my sword and did it. It was hard," Glanville said. "It was a onetime favor. Or it was supposed to be. You’ve all seen Lisa V. throwing that beautiful catered engagement party for that mistress at her house. Treating the mistress like family. It happened a lot. A lot."

Glanville and Scheana Marie's meeting at SUR Lounge, a restaurant owned by Vanderpump, was filmed for the first season of Vanderpump Rules, and made into a crossover episode with The Real Housewives of Beverly Hills.
