The epitome of overnight success, this former model went from TV guest spots (including a memorable recurring role as a judge's much-younger beau on Judging Amy) to headlining his own series, all in 2001. As a young Clark Kent on Smallville, Welling charmed viewers with his winning combination of stellar looks and boy-next-door vulnerability. Big-screen roles followed, yet the blue-eyed heartthrob remained inextricably linked to his small-screen alter ego. Off screen, Welling leads a low-key married life.
