The above sneak peek from Monday's show picks up just as Glanville, 38, is introduced to the cast by their mutual friend Adrienne Maloof at a party. "She's going through a divorce and I wanted to show her a good time," reasons Maloof.
But Lisa VanderPump isn't sold on Glanville, who is not joining the series as an official cast member.
"Who's that girl?" she snipes to Maloof, 49, in the clip. "I have seen pictures of [Brandi] in some gossip column hanging out with Cedric," VanderPump says of her former permanent houseguest turned foe Cedric Martinez. "My feathers are a bit ruffled before I even start."
And VanderPump isn't the only housewife who will clash with Glanville. As Maloof explains, the former model will make for must-see TV, especially when she bickers with the women.
"She kind of weaves herself in and out," Maloof confirms of Glanville, who was seen in the show's season preview trailer berating Kim Richards and threatening to kill her. "She is like bringing a child [to a party]. You don't know really what she is going to say. She has no filter, so that's why you want to stay tuned!"
The Real Housewives of Beverly Hills airs Monday at 9 p.m. (EST) on Bravo.
