In the snippet, the Biebs and his crew talk about how he's grown up since his last movie, Never Say Never, and even use his mustache as an example. LOL! Scooter Braun, JB's manager, is the first one to point out Justin's new facial hair.
"That's how much of a man I am," Justin says in the movie.
Bieber then proves his grown ways by expressing his love for coffee.
"Speaking of grown man, I'm drinking coffee right now."
Watch it all go down in the video above. Believe is set to his theaters this Christmas!
