Ian Somerhalder and Nina Dobrev have broken up, according to reports.
The Vampire Diaries co-stars, who play Elena Gilbert and Damon Salvatore on the hit show, recently called it quits after more than three years of dating.
The split was amicable, sources say, and won't be awkward on set.
They are "consummate professionals," an Us insider says, and "will continue to work together and remain best friends, which is where the relationship started."
It's unclear what prompted the breakup of the gorgeous, private duo, who were a favorite celebrity couple of so many fans since they got together.
Last fall, Nina opened up to Seventeen about falling for Ian.
"I didn't want to be dating one of my costars. But sometimes you can't help who you have a connection with, and you can only fight it for so long," she said.
"Which I tried, for a really, really long time."
In happier news, The Vampire Diaries was renewed for a fifth season, so you can at least appreciate their on-screen chemistry until at least May 2014.
