The video shows the Canadian popstar just being himself showing off his facial hair, drinking coffee and goofing around his friends.
Justin Bieber is a grown man now, so his manager Scooter Braun says in the first teaser of the singer's new docu-movie "Believe 3D". "This is how much of a man I am. #Stache!" the teen heartthrob says, as his manager pokes fun at his moustache. "Speaking of grown man, I'm drinking coffee right now," he adds before proudly taking a gulp from his cup.
Bieber's former mentor Usher and Bieber's mother Pattie Mallette also appear in the video. "As a 19-year-old, Justin is now becoming his own man," Usher says of his former protege entering manhood and maturity. Pattie, meanwhile, states, "I think it's hard for parents to let go, but it's really exciting to see him maturing."
The 3D movie will be released in the U.S. on Christmas Day this year. Following up the successful 2011 documentary "Justin Bieber: Never Say Never" directed by John M. Chu, it will focus on Bieber's transition from teen pop star to young adult during the making of his album "Believe" and the tour that followed.
