Pictures of AnnaLynne McCord, Jessica Stroup, Shenae Grimes in Bikinis on 90210 Set

90210 isn't back until Monday, but the cast was hard at work, if you can call lounging by a pool in the sun work, on set in LA yesterday. The midseason finale left us with a number of cliff-hangers and while it looks like things may turn out okay for the West Beverly High senior class, there's always drama in store. Jessica Stroup showed off her bikini body during the shoot and Jessica Lowndes sported a vintage-inspired one-piece, though AnnaLynne McCord stayed a bit more covered up than when she donned an ab-baring Avatar-inspired Na'vi costume last week.
