Amber Portwood -- The NEW Mug Shot


TMZ has obtained Amber Portwood's newest mug shot ... taken moments after she surrendered to police in Indiana yesterday.

We broke the story ... the MTV "Teen Mom" star was taken into custody after she told the judge she would rather serve hard time in prison than finish out the rest of her court-ordered drug rehab program.

Amber is currently at the Madison County jail ... where she will remain until a hearing is set. A judge will then decide how long Amber will stay behind bars.
