Justin Bieber: No More Pics With Fans ... 'I Feel Like A Zoo Animal'

Justin Bieber and the Siberian tiger at your local zoo have something in common ... they both want you to stop taking their picture.

The Biebs just posted an APB saying he doesn't owe his fans anything ... especially a duty to stand there while they photograph him. Bieber says, "I feel like a zoo animal, and I wanna be able to keep my sanity."
