Generally mug shots are an embarrassing affair for multiple reasons (more often than not) -- but Justin Bieber seems to be an exception to the rule.

Why? He took one of the most photogenic mug shots we've ever seen.

Seriously, he's even smiling! You'd think he was at a photo-call rather than a police station.

As we previously reported, Bieber was pulled over early this morning (around 4:00AM in Miami) for drag racing and driving under the influence.

According to a recently released police report, he was ultimately "charged with DUI, driving with an expired license and resisting an officer without violence."

Justin also "made some statements that he had consumed some alcohol, and that he had been smoking marijuana and consumed some prescription medication," based on a report from Miami Beach Police Chief Raymond Martinez.
