Justin Bieber suits up in Dolce & Gabbana for the June 2012 issue of GQ, featuring Michael Fassbender on the cover. During his interview, the 18-year-old singer was asked about his fame and alcohol.

On alcohol: “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.”

On fame: “I mean, I keep my guard up a lot, because you know, you can’t trust anyone in this business. That’s what’s sad. You can’t trust anybody. I learned the hard way.”

Vocal producer Kuk Harrell on Justin’s musical identity: “He knows his brand. If he hears something, he’ll go, ‘I think that’s me …’ The brand steers the ship.”
