The Vampire Diaries [1]' sixth season finale airs on Thursday, and that means only one episode left with star Nina Dobrev [2]. She stopped by Conan to chat about the series and to show off her impressive flexibility [3]. Though she doesn't get into details about the finale (we have pictures! [4]), she does talk about filming sex scenes with her mom on the set and how awkward vampire fangs actually are. She even puts on her fangs — well, Katherine's fangs. Take a look at the video below to see her pique Zach Braff [5]'s interest with some sexy stories.

And here she is teaching Conan O'Brien [6] to make a vampire face.
