Pro tattoo artists rip into Justin Bieber and other shitty pop stars for having crap ink

Seems like everyone is chucking ink on their bodies these days - and who could blame 'em? Tattoos are bloody cool... if you get them right. 

Sure, everyone has their own opinons on what's good and what's bad, but no one has better judgment on ink than the tattoo artists themselves.

Chris Nunez and Oliver Peck (who host a show called Ink Master) recently sat down for GQ and critiqued a bunch of crappy celebrity tattoos, including Justin Bieber, Rihanna and, of course, Mike Tyson.
