Nina Dobrev, a star of The CW's supernatural series "The Vampire Diaries," is leaving the show after this current sixth season. Dobrev, 26, posted on Instagram Monday that a weekend party in Georgia with the show's cast and crew "was a goodbye party. I always knew I wanted Elena's story to be a six season adventure, and within those six years I got the journey of a lifetime." Dobrev added she "made some of the best friends I'll ever know and built an extended family I will love forever." In May 2013, she and co-star Ian Somerhalder broke up after more than three years together.
