It's a sad day for Vampire diaries fans; Nina Dobrev and Ian Somerhalder have called it quits! The CW co-stars, who play Elena and Damon, have ended their real life romance after three years of dating. A source tells US Weekly that the pair are professionals and will continue to work together and remain best friends, which is where the relationship started. Last fall Nina dished to Seventeen Magazine about her relationship with Ian saying, I didn't want to be dating one of my co-stars. My goal on the show was to be professional, but sometimes you can’t help who you have a connection with and you can only fight it for so long, which I did for a really really long time.
