After getting a taste of stardom in "Twilight," Taylor had to fight to win back his role in "New Moon." To quiet producers' fears that he was too boyish to play the rapidly maturing werewolf, Taylor packed on 30 pounds of muscle. The dramatic transformation succeeded, and Taylor's abs helped him become one of the most desirable young stars in Hollywood. The ladies apparently took note, and he spent the next few years in a series of high-profile relationships with teen queens Selena Gomez, Taylor Swift, and Lily Collins, the co-star of his first starring vehicle, "Abduction." Now, the 20-year-old is one of the highest paid actors in Hollywood -- regardless of his underage status.
