Nina Dobrev and Ian Somerhalder of The CW's Vampire Diaries finally outed themselves as a couple earlier this year, and they weren't shy about sharing what they love about one another at the recent CW Premiere Party.  Ian said of Nina, "She truly enjoys life. Her desire to experience and appreciate everything around her, and chuckle and enjoy it, is great."  And then Nina countered with similar niceties about Ian, saying, "He always has a positive outlook and positive energy, and he's always happy. He is a glass-half-full kind of guy, not half-empty."  The third season of The Vampire Diaries premieres on The CW this Thursday night.
