41. Zac Efron
Look which High School Musical star is all grown up! Zac Efron broke out of his teen heartthrob shell and into manjoyment territory — check out those abs. Zac has quickly moved up on the PopSugar 100 list from his debut at 95 last year to 41 this year. He spent his Summer in Vancouver filming Charlie St. Cloud, took a quick break to accept a Teen Choice Award, and started promoting his other serious role in Me and Orson Welles by Fall. While his acting choices may have changed over the year, one thing was constant — his relationship with Vanessa Hudgens.
