Nina Dobrev's star continued to rise this year as her CW show, The Vampire Diaries, returned for a second season and her romance with costar Ian Somerhalder heated up. Her role on the show expanded to include both good girl Elena and evil Katherine, which gave Nina a chance to show off her range and have some fun. She scored the cover spot of Seventeen's special fitness issue this Spring, showing off her bikini body in the magazine, and even landed a role in The Perks of Being a Wallflower alongside stars like Emma Watson. Meanwhile, she and Ian — who were first spotted kissing last August — took their romance on the road. The cute pair even took their mothers on a vacation to Paris in May!
