AnnaLynne McCord: Dog Days of '90210'

AnnaLynne McCord is all smiles as she pets a dog on the set of 90210 on Wednesday (January 19) in Los Angeles.

The 23-year-old actress and her co-stars, Jessica Stroup and Jessica Lowndes, were also spotted chatting with each other during their breaks.

Jessica, 24, lightly covered her bikini body with a white sweater on the set then took some time to pose with fans.

FYI: AnnaLynne is the new face for Marc Ecko‘s Spring 2011 line and goes topless in the sexy new shoot.
