Hollywood hotties Dianna Agron, Jessica Szohr and AnnaLynne McCord all showed off their pins for the 2010 Breakthrough Awards held in California last night. Dianna chose a ladylike look for the occasion in an embellished floral Carolina Herrera frock teamed with Manolo Blahnik pumps; while Jessica waved the Aussie flag in a Ruby Smallbone dress mixed with Samantha Wills accessories. Go team Aussie! Pretty poser AnnaLynne took the Herve Leger route in a fitted green bandage dress mixed with statement earrings and nude heels. Help me out now peeps and tell me, who looked the most fab at the Breakthrough of the Year Awards?
