Even this time the news was spread through Twitter profiel 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 u can mysterious ster that is really him. Also to consider is that Selena Gomez and Demi Lovato are still good friends. Can u imagine singing along with Justin and Demi? What kind of song might sing a duet?
