Demi Lovato has a new duet in the works, and it sounds like it could be pretty epic too!

She posted the below photo to Instagram recently, not identifying who the person she's working with is.

A lot of people are speculating that it could possibly be Nick Jonas, but no one knows for sure what could happen.

I'm not sure it'd be Nick Jonas, but then again, who knows. J.T. possibly? Now I'm just throwing out random names :P
