Justin Bieber has learned a lot in Hollywood – and, unfortunately, not all of the lessons have been positive.
“I keep my guard up a lot,” the singer says in the latest issue of GQ. “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.”
Clearly, that’s not entirely true for the Biebs, considering his close relationship with Usher and, of course, with Selena Gomez.

Elsewhere in the interview, responds to a question about alcohol intake with:
“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.”
