Hear new single from Willow Smith, Will & Jada's daughter

It's been a good day for Willow -- the now one-named, 9-year-old daughter of Will Smith and Jada Pinkett Smith. Not only has her debut single "Whip My Hair" generated so much blogosphere heat that she landed on Ryan Seacrest's show, but she also got signed by Jay-Z's Roc Nation Records.

Now "Whip My Hair" isn't exactly groundbreaking, but not only is it as well produced as a Katy Perry single, it's just as much fun. (Did we mention that she's 9?)

"We at Roc Nation are excited to work with Willow," Jay-Z said in a statement. "She has an energy and enthusiasm about her music that is truly infectious.  It's rare to find an artist with such innate talent and creativity at such a young age.  Willow is about to embark on an incredible journey and we look forward to joining her as she grows in all aspects of her career."

Willow shoots a video later this month. Check the song out below.
