As fans of Twilight grow more mature, so do the sequels based on this popular vampire romance novel series. The first in a two-part finale, The Twilight Saga: Breaking Dawn - Part 1 is currently shooting in Brazil, and news has come forth from E! Online that Kristen Stewart will appear naked in the movie, giving the nearly always topless Taylor Lautner a run for his money.

Director Bill Condon is sticking fairly close to his source material in bringing Bella and Edward's Brazilian honeymoon to the big screen. There will be more sex than all three past Twilight movies combined, as the pair consummate their marriage before the camera. Condon will keep this final chapter within the boundaries of its PG-13 rating, but the current shooting script is reportedly pushing those boundaries, with Stewart set to strip way down to nothing at all.

Here is what a source close to the upcoming sequel had to say:

"The script actually has Kristen practically naked in it, a lot."

"Practically" means we won't be seeing any parts of her body that wouldn't make it past the MPAA in earning that PG-13. Though, as E! Online reports, Condon is the type of director who likes to keep it real, and he plans to bring a sense of authenticity to the lovemaking that will be on display in The Twilight Saga: Breaking Dawn - Part 1.
