Smile for the camera! Pop star Justin Bieber's mugshot has been released.

Following his arrest in Miami, Florida early Thursday (Jan. 23) morning, the Miami Dade County Corrections Department has released Bieber's mugshot. Apparently, the DUI arrest following a drag race hasn't soured Bieber's attitude; he's sporting a pretty big grin in the mugshot picture.

According to the NY Daily News, the other participant in Bieber's early-morning drag race, Khalil Amir Sharieff, was also arrested and charged with a DUI.

As for Bieber and his odd smile in the photo, one possible explanation is that the cop who booked the singer jokingly told him to 'smile for the camera,' and Bieber unwittingly obliged. Bieber looks far less pleased in the profile mugshot (pictured below).
