Well, that was fast. Nina Dobrev and Derek Hough have reportedly called it quits after only six weeks of dating. According to Us Weekly the couple had decided that the relationship had "played itself out" and that the distance was beginning to put a strain on their romance. (Derek is filming Dancing With the Stars in LA while Nina is working on The Vampire Diaries in Atlanta.) Derek and Nina went public with their relationship last week when they stepped out on a group date with friends. The two had been friends for some time before they started dating as Derek is the older brother of Julianne Hough, Nina's close friend.

Nina had previously been in a longterm relationship with her costar Ian Somerhalder. The two split up earlier this year.
