Los Angeles, Aug 4 (IANS) Actress Nina Dobrev will not be seen in the fifth and final season of the hit sitcom "The Vampire Diaries" spin-off "The Originals". Dobrov will not reprise her role as Elena Gilbert in the spin-off as she is currently busy with other projects, reports ew.com. "No, I will not be on 'The Originals', no," Dobrev said. "We literally just wrapped a few months ago. I doubt that would be in the books for me. But, yeah, no, I've been so busy with all kinds of other things going on right now that I don't know that I'd be able to sign on," she added. The 28-year-old said that being old is another reason why she opted for not appearing on "The Originals". "I'm not a young twenty-something anymore. I don't think I could play a vampire. I'm getting old," she said. "The Originals" season 5 is scheduled to premiere in 2018.
