Madonna is returning to the discothèque. Two decades after the release of her beloved album Confessions on a Dance Floor, the Queen of Pop has been hard at work on a sequel. "I'm putting my heart and soul into my new music," she wrote to her Instagram followers in February, "and I can't wait to share it with you!!" The timing for the follow-up couldn't be more perfect, as the original Confessions will turn 20 on November 15.
