The word on the street (literally, from fans) is that pop star exes Justin Bieber and Selena Gomez have recorded a duet together called "Unfamiliar". A group of potentially very lucky fans started the rumour on Twitter, allegedly live-tweeting it as Justin sang part of the tune to them. One fan tweeted:
"JUSTIN STOPPED FOR US AND ASKED US IF WE WANTED TO LISTEN TO A NEW SONG OF HIS AND ITS WITH SELENA" and "One of Justin's lines goes SOMETHING LIKE "dont you ever wish you said what you wanna say, or would you take it for granted."
No one can say whether it's true or not yet, but Justin has been teasing songs online while he's in the recording studio.
