Glanville, 38, shows up to a party with "Housewives" cast friend Adrienne Maloof, and immediately starts ruffling feathers, including those of Lisa Vanderpump, who has seen Glanville with one of her foes, Cedric Martinez.

Brandi, who is not a permanent "Housewife" on the show, will also clash with Kim Richards. As Maloof explains, the former model will make for must-see TV. "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 on Bravo.
