Kristen Stewart's bloody birth is undoubtely the most dramatic scene in The Twilight Saga: Breaking Dawn, however, new bloopers released from the films DVD extras show that Stewart and her co-stars Robert Pattinson and Taylor Lautner had some trouble getting it just right!

The young actors are unable to keep a straight face in the hilarious blooper video, where Pattinson is biting Stewart's arm and Lautner is attempting to give her CPR. At one point, Pattinson even had to walk away from where he was filming in order to get a good laugh out! Watch for yourself:

"She's just like...dead!" Lautner laughed. "Her mouth is closed and I've got to wrap my mouth around her lips and give her CPR. It ended up working, but it was funny at moments."

The DVD comes out on February 11 and I'm sure there's a ton of other totally laughable bloopers in there that I definitely can't wait to check out after seeing this one! Will you be picking up a copy of the film!?
