Things get a little explosive in the video for the Willow and Nicki Minaj duet 'Fireball.' The vid opens with Star Wars credits, with words ascending against a black, starry sky. Nice touch, ladies. While there is the requisite amount of flames for a vid for a song with the word "fire" in the title, the most standout thing about the urban, semi apocalyptic clip? The way Willow dances in the streets, with her long, coltish legs and exaggerated moves.
