WHO HE WAS THEN: Steve (1996-2002), a pastel dog's best friend on Nickelodeon's Blue's Clues.

WHERE HE IS NOW: Probably on a stage, performing songs from his well-reviewed Songs for Dustmites, a CD of Foo Fighters-style rock. The Brooklyn, New York resident is currently on tour, but don't take the toddlers to the show. "We can roll around on my floor/That's what it's for," he sings. Sounds like Steve is all grown up.
