The Vampire Diaries star, who took the stage in a green Elie Saab dress, thanked the show's fans for their furious writing campaign to get her nominated.
"Wow guys," Dobrev said on accepting the award. "This is so great. "I honestly wasn't even initially nominated at all," she continued. "I wasn't on the ballot."They caved in and gave me a nomination, and now I get to take this to Atlanta. Thank you everyone and thank you to the fans. I love you guys." Dobrev then blew the audience a kiss as she left the stage.
The Vampire Diaries is also nominated for 'Favourite Sci-Fi/Fantasy Show' and 'Favourite TV Drama', while show star Ian Somerhalder is nominated for 'Favourite TV Drama Actor'.
Nina, too, has been tweeting up a storm about the PCA's, gushing to her followers, "Thank you for making my dream come true." She also tweeted, "Having a burger as a post award show celebration!"
In honor of Nina's big win, here's a slideshow of some of the always-classy star's most gorgeous red carpet looks.
