JUSTIN BIEBER suited up and talked about alcohol and KIM KARDASHIAN as he was featured in a video clip by “GQ.”

Yes, the boy has indeed grown up… a bit.

Justin, who pretty much looked like himself on the ”Saturday Night Live” 100th digital short, talks about the absence of the usual vices in his life (well, just beer) and his views on his friend Kim Kardashian in the upcoming issue of “GQ.” And it looks like he had a blast at the shoot, too!

The pop star revealed in the clip that he actually stays away from alcohol and other bad influences, unlike many young stars who’ve hit mega stardom.

Bieber tells the mag:

“I keep my guard up a lot, because you know, you can’t trust anyone in this business.”

He continues:

“That’s what’s sad. You can’t trust anybody. I learned the hard way.”

Although he doesn’t open up on how he learned his lesson, we think it may be related to his very little to none affection for alcohol and drinking, as he says:

“For me, it’s just like, I like to be in control of myself. [I've] had a beer, like, before…. but I never get out of control.”

Biebs also talks about his famous friend Kim Kardashian, and no, not because of their controversial flirty shoot by the beach before. The pop star merely reacts to a member of his entourage who made fun of her by calling critics “so mean,” and adding:

“People say [Kim] doesn’t do anything; she actually does do stuff. She works hard.”

We have a feeling that he was speaking for himself, too.

Check out the behind-the-scenes clips of his shoot:
