Ian Somerhalder was in New Orleans yesterday, getting a drink at a gas station before split from longtime girlfriend Nina Dobrev. Nina, 24, and Ian, 34, had been together for about three years, and apparently grew apart despite logging long hours on the set of their show together. Neither Ian nor Nina have commented on the breakup, but he did post a mysterious tweet just after news of their parting ways broke. He referenced playwright Lillian Hellman's quote, "People change and forget to tell each other." Another chapter is coming to a close for Ian, with the Vampire Diaries' season finale airing Thursday.
