Asked if she can relate to most ten-year-olds, Willow Smith doesn't miss a beat. "Of course—I am one!" she says, stopping just short of letting out a giant "duh."
But it's not exactly the stupidest query in the world, since, at least on the outside, Willow has the kind of life most fifth graders don't: movie-star parents (Will Smith and Jada Pinkett-Smith), a famous big brother who's BFFs with Justin Bieber (The Karate Kid star Jaden), a film career of her own (Kit Kittredge: An American Girl and I Am Legend), and, of course, one megahit song.
Unless you don't have a radio, TV, or Internet connection, you've probably heard the übercatchy "Whip My Hair," which, since its release this fall, has scored more than 34 million hits on YouTube and a number eleven slot on the Billboard Hot 100—a milestone no other ten-year-old has reached.
Willow, who joins Justin on his European tour this month, admits that even she's still getting used to it all. "When I first put ['Whip My Hair'] out, everyone was like, 'Willow, Willow, I love your song!' And I was like, 'Really?'" recalls the singer.
