Young Willow Smith gave fans a listen to her newest single "21st Century Girl." It debuts on On-Air with Ryan Seacrest Monday morning, will be performed live on Oprah for a worldwide broadcast premiere, and a video has already been shot, and it's available for sale on iTunes this Tuesday. This same snippet hit the blogs months ago, but a good percentage of her fan base isn't scouring sites for leaks, and Willow and her team are handling it as such. The follow-up to "Whip My Hair" is certainly being rolled up the right way. Let's see if she can score another hit.
