Nina Dobrev wore J. Mendel to hit the red carpet at this evening's Teen Choice Awards in LA. She didn't pose with her real-life boyfriend, and The Vampire Diaries costar, Ian Somerhalder. Ian, though, was not too far away posing for pictures of his own. It's a big evening for Nina, Ian, and their series. They're up for individual honors in the categories of choice actor and actress in a fantasy or sci-fi show. Ian's also up for the coveted male hottie honor. There could be celebrating to do with their fellow leading man Paul Wesley if The Vampire Diaries beats Fringe, Once Upon a Time, Supernatural, and True Blood to win choice TV show: fantasy/sci-fi.
