Guess Which Rap Mogul Just Signed Willow Smith?

Willow Smith is having the best day ever.

In the 24-hours since her blazing new single  'Whip My Hair' leaked, the fashion-forward  9-year old has been the talk of the music industry - with everyone from Solange to Jazmine Sullivan singing her praises. Now, it has been confirmed that she is latest artist to sign to Jay-Z's label  Roc Nation.

The rumor mill has been buzzing about this signing for a while, and now that it's officially confirmed we can say two things : 1. Willow is about to be the biggest thing in music. 2. Jay-Z is a genius. We're looking forward to hearing Willow's album, hopefully her father makes a guest appearance!
