Enjoying some alone time together now that they're married, Edward and Bella play a game of chess. 

The actress addresses her skinny look during the dramatic pregnancy in 'Breaking Dawn.'

True blue Twilight fans may be shocked at how much weight their heroine Kristen Stewart lost to appear emaciated and ill during Bella Swan's pregnancy in The Twilight Saga: Breaking Dawn Part 1. Sure there was some hollowing and shadowing facial makeup. But at the film's junket at the Four Seasons on Thursday (Nov. 3) Stewart was asked about the drastic dieting she must have had to endure to get so darn scrawny.

"Digital. Totally. I didn't have time to lose any weight," Stewart explained. "All the scenes were so sporadically shot. As Bob [Condon] said, In one day, I literally was a vampire, a human, a pregnant woman, about to get married. Everything was shot completely out of sequence."

That made real weight loss impossible. "We would have had to shut down production for a couple of months for me to lose the weight or gain it back, either way. So it does make you feel, 'Well, I hope you guys do a good job with it because I can't do that part.'

"It can ruin you if you look ridiculous and obviously, I don't," the initially worried Stewart confided. "Those guys are amazing."

The Twilight Saga: Breaking Dawn Part 1 opens on Nov. 18. But you probably already knew that.
