Kristen Stewart Says "Twilight Saga" Ends with a Huge 'Twist'

Michael Tran/FilmMagic(BURBANK, Calif.) -- On Monday's installment of The Tonight Show with Jay Leno, Twilight series star Kristen Stewart plugged the saga's upcoming final chapter, The Twilight Saga: Breaking Dawn -- Part 2.  Not surprisingly, she didn't mention her relationship with co-star Robert Pattinson, which apparently weathered a cheating scandal.

However, the actress, often seemingly indifferent towards promoting the vampire films that made her a household name, gushed about the ending of the series.

"It's just so shocking to be honest," Stewart said of a twist that apparently ends the final film.  "I couldn't be more inside of it, I couldn't be more in the loop, and every time I see it, or even think about it, I get like giddy, it freaks me out."

For the purists of Twilight author Stephanie Myers' books, Stewart insists the shocker is on the level.

"It's easy to skim over, but you can find the root of our little twist," she explained.

The Twilight Saga: Breaking Dawn -- Part 2 hits theaters Nov. 16.
