Considering Kelly took time out of her schedule to learn Demi's new song and cover it for her this year for her birthday I'm pretty sure Kelly would do something like this if asked. If she did get Kelly to do this I wonder if Demi would give Kelly the honor of revealing the name of the title track (if there is one), or maybe let her be the one who reveals the final track.
If she got Kelly to announce the album name, that would be AWESOME. I'll settle for the final track, though.
