JUSTIN TIMBERLAKE
AGE 27

BROKE OUT IN... guest-hosting gigs on Saturday Night Live. Sure, Alpha Dog showed his serious chops, but few saw it. The memorable “Dick in a Box” skit on SNL showcased his comedic side.

WHAT'S NEXT Timberlake continues to go for laughs, starring alongside Mike Myers, Jessica Alba, and Meagan Good in this summer's The Love Guru, a comedy where he plays a girlfriend-snatching skater.
