No. 7: Willow Smith
Birthdate: October 31, 2000 (age 9)
Why She's Hot: Willow Smith will never forget the summer of 2010. The nine-year-old daughter of actors/musicians Will and Jada Pinkett-Smith officially launched her music career in September when she released her contagious first single, "Whip My Hair," which immediately drew comparisons to pop diva Rihanna. Just a few days later, the fashionable pint-sized singer was signed to none other than Jay-Z 's Roc Nation label and is rumored to be starting her own clothing line. She recently released a teaser to the video and is said to begin working on her debut project soon. Big brother Jaden  may have the eyes of Hollywood on him, but it's Willow who is going to own your ears.
