Popsugar recently did an interview with The Twilight Saga screenwriter Melissa Rosenberg. She has penned the scripts for all four films.

Warning: Spoilers below!

During the interview Rosenberg had a chance to clarify comments she had made in an earlier interview with the The Los Angeles Times regarding what viewers should be exposed to when Bella gives birth to her and Edward's child in The Twilight Saga: Breaking Dawn.

"That was a misquote. The childbirth - all the scenes, I feel - should be on screen. I think perhaps what I was referring to was, would we actually see Edward's teeth through the placenta? I don't think so. I don't think we need to see that, and if someone needs to see that, I think they should take a look at that. [Laughs.] I believe it will be implied, but I don't think we'll see teeth in the placenta."

Rosenberg also discussed the changes we are going to see in Bella during the much anticipated fourth film:

"I think seeing Bella as a vampire and her adjusting to her powers and embracing them, those are all really fun scenes to write. Particularly when you picture Kristen Stewart playing her, and the way she's embodied Bella as a sort of awkward, fidgety persona. When she turns into a vampire, all of that goes away."
