Adnan Ghalib, Britney Spears' ex-boyfriend/paparazzo, was booked into jail on Friday -- and here's the mug shot. Soul patches are all the rage in prison.

He'll be doing 45 days in the pokey and was also on formal probation for 36 months and has to complete 52 weeks of anger management classes and 45 days of Caltrans (hard labor).

Back in October, Ghalib pled no contest to leaving the scene of an accident after he allegedly ran over a process server in February.

The process server who was allegedly hit by a Mercedes driven by Adnan Ghalib made it clear in a court declaration -- Adnan could have killed him.

Ram Moskowitz (first name, first clue) claims when he tried serving Adnan with Britney Spears' TRO, Adnan gunned his car and hit him. The force propelled Ram onto the hood. He claims "I stayed on the hood ... for about 30 to 40 yards, at which point I was thrown off..."

Ram suffered cuts, abrasions and a fractured wrist. Adnan has been charged with three felonies.
