It was a bikini-filled day on the set of 90210. Jessica Stroup, an Agent Provocateur-wearing AnnaLynne McCord, and Jessica Lowndes wore their swimsuits today to film a scene in LA. It was the latest instance of AnnaLynne in a bikini on set, as she donned a hot-pink two-piece to shoot solo last Thursday. The two Jessicas, AnnaLynne, and their fellow leading lady Shenae Grimes are gearing up for the fifth season debut of their show on Oct. 8. The last season was full of shocking moments, including an almost-wedding for AnnaLynne's character Naomi. Will you tune in to see the new episodes of 90210 this Fall?
