Vampire Diaries pair Nina Dobrev & Ian Somerhalder Split!

Vampire Diaries co-stars Nina Dobrev and Ian Somerhalder have been together since 2011. The couple has been very secretive about their romance, but now they do not need it anymore - because it's over.

They will "continue to work together and be best friends, which is where the relationship started from scratch," says an insider. Vampire Diaries is currently in its fourth season, and has been confirmed for a fifth, which will involve both actors.
