Does Justin Bieber modeling menswear mean he's officially a man?

Sure, Justin Bieber might spend some of his time writing super mushy songs for his mom on Mother's Day, but let us not forget that this kid is still a mack. Thanks to the Biebs' new spread in GQ, I'm feeling really conflicted -- I'm not sure if I'm even allowed to think that Justin now looks like a male model, let alone wish he was my steady boyfriend.

Inside the issue, Justin comments on everything from partying hard to his views on Kim Kardashian. On going out and raging, JB explains, "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." We, like, believe you, Justin. On his famous pal and the leader of the Kardashian clan, JB defends her: "People say [Kim] doesn't do anything; she actually does do stuff…. She works hard." (Of course you'd say that JB -- you're the consummate gentleman).

In more breaking "Justin Bieber is now a grown-ass man" news, Justin recently tweeted a link to his Viddy account, directing fans to a clip of himself going FULL ON SHIRTLESS for a photo shoot. Not to be really stalkerish or whatever, but last time I checked, Justin did NOT have that kind of ab situation going on. Aaaand I'm gonna stop myself right there -- I don't wanna make anyone uncomfortable.
