Even this time the news was spread through Twitter profile because its producers Demi wrote: "Wow, today we had a special guest in the studio. We are thinking of a duet, "and then a follower of the producers of Demi commented:" It 'very possible that Demi duets with Justin Bieber. "
Although there is still no official seems that the "scoop" can be trusted: in those days Justin was in Florida for the concert of his girlfriend, just an hour's drive from Miami, so you can mysterious star that is really him. Also to consider is that Selena Gomez and Demi Lovato are still good friends. Can you imagine singing along with Justin and Demi? What kind of song might sing a duet?
