Are you ready for Willow Smith? The 9-year-old daughter of Will Smith and Jada Pinkett Smith released her first single, 'Whip My Hair,' with Jay-Z's Roc Nation label, readying her place as the heir to her father's musical throne.

Willow has become a red-carpet staple in recent months, turning heads with her out-there fashion choices. She delivers that same swagger in her song, rapping that she's not doing anything wrong, just trying to have fun and will "keep fighting until I get there."

So, is it too early for Willow to start a music career? She's certainly a little younger than her dad was when he burst onto the scene as the Fresh Prince, but plenty of kiddie acts have made it to the big time -- just look at the entire cast of 'The Mickey Mouse Club.' Check out some of our favorite kids who've gone on to bigger and better things after the jump.
