Justin Bieber was pulled over in Calabasas this morning for wild driving - and during the stop, cops discovered the pop star shouldn’t have been on the road in the first place … ‘cause he’s NOT licensed to drive in California.

Law enforcement sources say that cops noticed Justin’s white Ferrari blowing through a stop sign near his Calabasas home around 4:30 AM Wednesday morning. 

Justin was cooperative during the stop - but cops noticed that JB did not have a valid California driver’s license, something new residents of the state are required to have within 10 days of moving to CA. 

Sources say Justin was cited for running the stop sign and for being unlicensed. JB was ordered to get out of the driver’s seat - and his passenger was allowed to drive the car home.

If Justin wants to get back behind the wheel - he’ll be required to hit up the DMV first and obtain the proper CA driver’s license … and if he wants to make that happen by the end of the day, he should probably get in line now.
