It's official! Nina Dobrev is returning to The Vampire Diaries for the final season. The actress, who famously left the show at the end of season six, announced the exciting news on Instagram by sharing a picture of her script. "I know it's Thursday, but this is not a TBT. #BackOnSet #TVDForever," she captioned the post. While it is unclear whether she'll be reprising her role as Elena or Katherine, we are certainly happy to hear she's coming back!
