Justin Bieber Dismisses Talk Of Collaboration With One Direction

A representative for Justin Bieber has dismissed rumours the pop star has teamed up with One Direction on a new track after singer Niall Horan sparked speculation of a collaboration.

He posted: "In the studio with our boy Justin Bieber last night, it's gona (sic) sound great!"
