Willow Smith has revealed a new song called 'Why Don't You Cry'.

It's the 14-year-old pop star's latest endeavour, following the release of 'F Q-C # 7' earlier this year.

The video - which was conceived by the youngster herself, dontcha know - depicts the singer crying in the midst of an argument between two adults.

It also stars her half-brother Trey aka DJ Ace, Will Smith's son from a previous relationship.
