Lautner was 16, and the youngest of the "Twilight" stars, when he took on the role of Jacob. Before becoming a teen idol, he was a child star with film credits including "Cheaper by the Dozen 2" and "The Adventures of Sharkboy and Lavagirl 3-D."
He's become famous for his plethora of shirtless scenes, but Lautner isn't all muscles and good looks. After finishing high school, he entered community college, but due to "Twilight's" fame, he was unable to finish, he told David Letterman. One day, he might return, he said, "as long as I'm not working."
Lautner's schedule doesn't appear to be freeing up any time soon. He recently wrapped "Grown Ups 2" in which he plays a frat boy and he is signed on for "Tracers," which is set to premiere in 2014.
He's has also been busy dating. The actor has been linked to Selena Gomez, Lily Collins and most recently, his former high school girlfriend, Sara Hicks. Lautner had a very public relationship with Taylor Swift in 2009 but the pair split after just three months. Now 21, Lautner said in an interview in the December issue of Cosmopolitan that he keeps a good relationship with all of his exes, including Swift.
