Taylor Lautner hit the gym today on his 18th birthday, and we all have something else to celebrate! Last night a source broke the news to us that the final Twilight saga installment, Breaking Dawn, will in fact be two movies. Apparently they are putting the finishing touches on the two scripts, which must mean that Robert Pattinson, Kristen Stewart, and Taylor Lautner are all in for it! There have been rumors for months that the epic fourth book will become two movies, and now it's official — we can't wait for more details. Where do you think Breaking Dawn should get split up? Happy birthday to Taylor and happy more Twilight day to us!
