The two had stepped onstage to pick up their much-deserved award for "Best Chemistry," which they managed to maintain for months onscreen after their breakup last May.
Dobrev and Somerhalder sat next to each other during the show, and even attended a fitting together with their stylist Ilaria Urbanti.
Somerhalder also took to Twitter to wish his ex, who turned 25 on Thursday, a happy birthday.
Happy Birthday @ninadobrev !!! The world loves you!We all do;) Enjoy the moment, enjoy the day,enjoy the year!— ian somerhalder (@iansomerhalder) January 9, 2014
