DMX -- The Newest Mug Shot

7/26/2010 7:55 PM PDT
TMZ has obtained DMX's latest mug shot -- taken moments after he turned himself in to authorities in Los Angeles today.

As we first reported, DMX was ordered to serve 90 days in jail in connection to a reckless driving conviction from way back in 2002.

If DMX looks relaxed in the mug shot ... it's because he's taken about a million of them.
