Approaching new heights of manhood and maturity, Justin Bieber sports a manly mustache in a new promo for his upcoming movie, "Believe."

In the clip, just released today (October 11), the "Biebs" tells his manager Scooter Braun he’s a “grown man,” while Usher and mom Pattie Mallette give interviews about the performer’s maturity.

The preview features footage from the 19-year-old pop star’s “Believe” tour, and the movie, scheduled for release this Christmas, will combine documentary footage with fictional sequences.

One such fictional scene finds Justin dodging the cameras and running through a warehouse in L.A., before testing out a more violent way of dealing with pesky paparazzi.
