Justin Bieber

Justin Bieber is all grown up—kinda.

In a new interview with GQ, the 18-year-old pop star opens up—hesitantly—about his life as a "swaggy adult."

When asked by the interviewer if he's ever gotten "s--tfaced," he explains eloquently: "For me, it's just like, I like to be in control of myself. I mean, I've had a beer, like, before…But I never get out of control."

The Biebs is also quick to defend our girl Kim Kardashian after one of his "business advisors" insults the reality star.

"You guys are so mean, bro," he says indignantly. "People say she doesn't do anything; she actually does do stuff…She works hard."

Bieber works hard himself, and he's proud of his accomplishments. "I've never made a bad song," he says.

And of course, like any teenage boy, he wants to reap the rewards of his hard work. During the interview, his tricked-out Mercedes-Benz Sprinter van arrives. It's got three HD TVs, a computer dock and a fully operational recording studio. His friends try to guess how much it costs, and one reasons, "Definitely not a million."

Hey, whatever amount this swag van set the Biebs back, we're pretty sure he can foot the bill.
