90210

The girls of 90210 and The Real Housewives of Beverly Hills are colliding in their shared zip code.

In an upcoming episode of The CW series, airing Monday, March 11 at 9/8c, Naomi (AnnaLynne McCord), Silver (Jessica Stroup) and Adriana (Jessica Lowndes) have a wild out and meet Housewives Camille Grammer and Brandi Glanville. In our exclusive first look, the girls track down Grammer and Glanville at the Pilates studio when they can't remember the events of their crazy night. (Knowing the Bravolebrities, it probably involved booze, boys and a brawl.)
