'The Vampire Diaries' star Nina Dobrev will make a guest appearance in spin-off 'The Originals'.
Dobrev, 25, will portray a new doppelganger of Elena Gilbert known as Tatia, who insinuates herself between brothers Klaus and Elijah, reported Ace Showbiz.
"There was a character's name introduced a long time ago in season three in association with Klaus (Joseph Morgan) and Elijah (Daniel Gillies) and how they became vampires and a girl that they both loved a long time ago who was the original doppelganger, Tatia," 'Originals' producer Julie Plec said.
"So Nina Dobrev will be visiting 'The Originals' for a nice little storyline in our fifth episode which airs November 3."

Dobrev has portrayed three characters - Elena Gilbert, Katherine Pierce and Amara - in 'The Vampire Diaries'.
'The Originals' returns on October 6.
