Yep, mystery surrounds just how many tunes Demi and Nick have sung together that just may or may not ever make their way to our earholes.
In a recent interview with On Air with Ryan Seacrest, Nick was asked if he and Demi worked on more songs than just the duet "Avalanche" together. He revealed: "There is. There's a bunch. Demi and I are great friends and have collaborated a bunch of times in the past. Some of it's come out, some of it hasn't. So, hopefully over time some of the other ones we did will come out. There's a song called 'Afterglow' that I'm really excited for people to hear one day."
Don't make us wait too long!
