Disney's new live-action adaptation of Beauty and the Beast is set to hit theaters next week. In advance of the big event, a promotional music video has just been released, featuring John Legend and Broadway's own Ariana Grande (13) singing the show's iconic title song. The enchanting four minutes finds Grande and Legend singing at a piano in the ballroom of the Beast's castle, with the Beast himself (played by Dan Stevens) and Belle (Emma Watson) making cameo appearances.
