Justin Bieber Plays Dress-Up For GQ [Photos]

Aw, how adorbs. Justin Bieber thinks he's a man.

The 18-year-old pop star and recent high-school graduate deserves credit: he cleans up pretty nicely. Still, there's precious little denying that the image he's projecting with these five shots accompanying his recent GQ interview don't so much scream "I am a man!" as "Zach Morris is back, y'all!' Oh, well. Anything to remind the public that his new album Believe hits stores very, very soon.

*Sniff, Sniff* They grow up so fast. One day, they're soiling diapers. The next, they're YouTube sensations with homemade performance clips gathering views by the millions. Then before you can blink, they look like they're playing dress-up in Dad's Armani suits and defending the value to humanity of Kim Kardashian.

Wait a sec....

That's right, Bieber recently experienced a "Leave Britney alone!" moment when an entourage underling was reportedly talking smack about the most infamous Kardashian sister. As he told GQ, the two are apparently friends going way, way back.

"You guys are so mean, bro....People say she doesn't do anything; she actually does do stuff....She works hard," Bieber said, without specifying   exactly into what she puts all that "hard work."

See, while Bieber may not be everybody's cup of tea, he has an obvious marketable skill - he has a singing voice that many enjoy. Kardashian's creative opus so far has been playing "Hide The Sausage" on camera with Brandy's little brother.

That's not to say Bieber himself doesn't shamlessly cut loose. Oh, beware this party animal.

"For me, it's just like, I like to be in control of myself," he added. "I mean, I've had a beer, like, before...But I never get out of control."
