Then: Cross-dressing as LaToya, a vivacious convenience store clerk.
Now: After Amanda Bynes, maybe the most active former cast member. His Nick Cannon Show spun off of All That in 2002, and he parlayed it into Wildin' Out on MTV and a stint hosting America's Got Talent. On the big screen, he's appeared in Drumline, Love Don't Cost a Thing and 2008's Day of the Dead, and he attempted a rap career in 2003. Perhaps more notably, he got hitched to Mariah Carey in 2008.
Then: Stuart, the spazzy infiltrator.
Now: Has taken a far less spastic turn as Intern Steve on recent episodes of Grey's Anatomy (here, he's the one with the busted arm).
Then: Babbled about pressing world issues in “Baby Chat.”
Now: Only on the show a few months before its 2000 cancellation, Iglesias is now best known for his recent stand-up act—specifically, as the “I'm not fat, I'm fluffy!” guy.
