While Twi-hards were on pins and needles during the birthing scene in 'The Twilight Saga: Breaking Dawn - Part 1,' it actually took a few takes to get the intense scene locked down, no thanks to Taylor Lautner and Robert Pattinson cracking up during filming.
In a new bloopers clip from the movie, fans can see Rob bursting into laughter while sinking his teeth into Kristen Stewart's arm. Meanwhile, Taylor couldn't keep it together while attempting to resuscitate Bella.
"There was one point when she stops breathing and she's out of it and I have to give her CPR," he says." There was some moments during that we couldn't keep straight faces."
He adds, "She's just like dead, and her lips are closed and all of a sudden I gotta wrap my whole mouth around her lips and give her CPR. It ended up working but it was funny at moments."
Check out the bloopers below, and get ready for 'The Twilight Saga: Breaking Dawn - Part 1' to be released on DVD and Blu-ray on February 11.
