Adnan Ghalib -- The Mug Shot

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.
