Willow Smith, Jessie J Perform on 'X Factor' [Video]

Willow Smith blazed the stage on Thursday’s “X Factor” results show with her brand new single “Fireball.” The 11-year-old Roc Nation signee and her Warriorettes crew powered through a high-energy performance that had the judges on their feet.

In addition, a blue-haired Jessie J traveled across the pond to hit the stage on the U.S. version of the singing competition, serving up her Dr. Luke-produced single “Domino.”
