Tuesday marks the release of Twilight Forever: The Complete Saga on DVD and Blu-ray. Other than a high-definition look at Edward’s sparkling skin, this DVD set also comes with some special behind-the-scenes clips. For instance, did you know that Kristen Stewart got her rear end ‘molded’ in order to create a device that would help Taylor Lautner carry her around for long periods of time (think Jacob and Bella’s walk through the woods inEclipse)? Well, thanks to an exclusive behind-the-scenes look, we have proof.

Turns out, Lautner carrying Stewart while reciting three pages worth of dialogue wasn’t as easy as it looked, especially after the third or fourth take. “I literally went and got my rear end molded to make this day easier on Taylor,” Stewart says. Check out the video below:
