Justin Bieber’s A-list Collaborators: Usher
As Bieber’s mentor and certified “big bro,” Usher first collaborated with the Canadian pop star on a remix version of “Somebody to Love,” the second single from My World 2.0. Since then, the R&B artist went on to appear in Bieber’s concert documentary movie, Never Say Never, as well as a cover of “The Christmas Song” on his second studio album, Under the Mistletoe. Back in April, Justin hinted there would be new collaborations on their respective forthcoming albums, but Looking 4 Myself and Believe didn't deliver another duet. That's not to say that Usher didn't play a major role in the Biebs' latest offering — he's the LP's executive producer, after all.
