“You will see sex – Yes!” Breaking Dawn and Twilight screenwriter Melissa Rosenberg told PEOPLE at the Eclipsepremiere in L.A.

“The relationship [between Robert Pattinson’s Edward and Kristen Stewart’s Bella] does go all the way in the book, so in the movie, it will as well. You are going to see more skin in Breaking Dawn than you did in the other films.”

So can we expect soem XXX scenes?

“Will it be pornographic? – That, I do not know,” Rosenberg said with a laugh. “I don’t know if it has to be R-rated, but it has to be what the book is, which means more skin. … I will definitely be writing more skin.”
