Ian Somerhalder and Nina Dobrev have broken up according to Us Weekly Magazine. Somerhalder and Dobrev began dating in 2010 and star in the hit series The Vampire Diaries together.
Somerhalder and Dobrev are "consummate professionals and will continue to work together and remain best friends, which is where the relationship started,” the source told Us Weekly.
The couple has been together for three years, but did not go public with their relationship until 2011. Last year, Dobrev talked about her relationship with Somerhalder and how it started.
"I didn't want to be dating one of my costars -- my goal on the show was to be professional," she admitted. "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."
Reps for Dobrev and Somerhalder did not comment on the split to Us Weekly.
