Demi Lovato is working on new music, and she’s invited a very talented collaborator in on the process.

The “Stone Cold” singer tweeted last night (April 11) that she and Miguel have written a song together. Miguel confirmed the collaboration, tweeting that their new track was “such a great wave" (a reference to his Wildheart single "Waves").

A few days ago (April 8), Lovato noted that she’d been recording with another mysterious collaborator. "Recorded something in the studio today with someone so talented and I'm so excited for y'all to hear it,” she tweeted.

If the past week is any indication, the follow-up to Confident will be a star-studded affair.
