Brace yourselves, Twi-hards: The ending of "Breaking Dawn, Part 2" might not be the one that you know and love from the Stephenie Meyer book when it plays out on the big screen this month.
"Twilight" star Taylor Lautner -- who plays werewolf Jacob Black in the hugely successful vampire movie series -- admitted during his interview with "Tonight Show" host Jay Leno on Wednesday night that the final film of the series, "The Twilight Saga: Breaking Dawn - Part 2," will deviate from the book it's based on.
"[T]here's a twist, because the ending -- I don't wanna give anything away -- is a little different from maybe, what was in the book," Leno said.
"You know," Lautner said, "there's a very thin line, because the fans would freak on us if we changed anything too much ... I can confirm there is a twist, and I can confirm everybody can find out what it is on Nov. 16."
So ... it'll turn out that they weren't really vampires after all?
