Whoa! What the hell is Justin doing to his body?!

Well, some Beliebers like it, but others are freaking out -- in a bad way -- over Justin Bieber's new HUGE chest tattoo that he debuted on Instagram Saturday.

Some reports claim Justin has more than 60 tattoos -- he even has that tiny cross on his face. His chest used to be a massive "Son of God" ink and now that seems to have been incorporated into this new art and we can't even figure out what it is! Weigh in with your thoughts in the comments ...
