ET spoke with Keys in May during a red carpet for season 12 of The Voice, where she shared details about the follow-up to her 2016 album, Here.
"I'm about halfway," she said of her new LP. "I'm ready for the next one already, which was kind of the plan the whole time. I wanted to put out Here where they have a statement body of work, and my next body of work is already in the works. I'm excited!"
Keys also mentioned that she isn't returning to The Voice, but is excited for fans to hear new material.
"I can't wait for you to hear new music, and so that's one of the reasons why I won't be able to come back next season," she added. "But I love writing. It's just the most beautiful, exciting thing, and every time I get better. That's the blessing and magic of writing."
