Good news for Demi and Miley fans! The teen queens are set to colloborate together to a duet on Demi’s new album along with another teen star Justin Bieber! Earlier this week, Miley flew in to NYC to sing with Bieber at his concert in NYC. I think they did an amazing job together singing “Overboard” and with Demi Lovato, it would be even better! With Demi, Miley and Bieber, I think the song is going to be a hit!
