After creating buzz for his highly-anticipated documentary, Believe, by asking Beliebers to piece together the movie poster via an Internet scavenger hunt, Justin Bieber dropped the official trailer on Friday.

The movie trailer opens with scenes from one of JB’s high-energy concerts, and it also gives fans a glimpse of the mayhem that surrounds his rock-star lifestyle, using real-life clips from his paparazzi encounters, including one when he was physically restrained by his bodyguard from going after a photog.

The pop star even dishes on his controversial scuffle with the paparazzi in March, and his saggy pants — which his mom, Pattie Mallette, calls him out on. “I’m still your mom, and I still want you to pull your pants up.”

Believe is slated to premiere on Christmas Day.
