They say that all good things come in threes, and that’s certainly true when it comes to the McCord sisters!

90210 star AnnaLynne McCord was the main attraction in a tight-fitting olive Herve Leger bandage dress as she picked up the award for Breakthrough Stand Out Performance at the Breakthrough Of The Year Awards presented by Crest 3D held at the Pacific Design Center in West Hollywood on Sunday, but her beauty and sense of style definitely runs in the family.

The petite star was flanked on both sides by her supporting cast, two sisters Rachel (left) and Angel (right). Originally from Georgia, the Southern babes are often spotted out on the town in Hollywood together.  Rachel and Angel have clearly been learning from their famous sibling, as they blew kisses to the cameras and posed like true professionals!

AnnaLynne was also joined by her equally perfect 90201 co-star, Jessica Stroup in a white one-shoulder dress, and Gossip Girl Jessica Szohr (squeezed into a cutting edge black Ruby Smallbone mini dress and sparkling Bulgari serpent ring).
