The film will apparently highlight Bieber's transition from teen pop star to young adult. In the preview's opening scene, Bieber's longtime manager Scooter Braun is seen poking fun at the singer's mustache. With his voice cracking, Bieber quips: "This is how much of a man I am," while #STACHE flashes across the scene.

It's a safe bet that Believe will be chock-full of hashtags, as the singer posted the video alongside the hashtag #FilmFridays on Twitter. On Monday, Bieber kicked off his own contribution to the growing Twitter trend #MusicMonday, debuting his newest single "Heartbreaker" and promising to release one new song every Monday for 10 weeks as a lead-up to his film's release.
