The mug shot from Amber Portwood‘s latest arrest was released today and, needless to say, the Teen Mom star doesn’t look too happy.

As the perennial Mother of the Year candidate cools her heels behind bars, more details are emerging about the latest in a long line of legal setbacks for Amber. It seems the “mood altering substance” she was on at the time of her arrest was some kind of prescription pill, several of which authorities found in her purse. Not surprisingly, Amber was unable to furnish a prescription for the pills.

A probation violation hearing is scheduled for January 13, which means Classy-pants Portwood will likely be spending Christmas in the clink for the second year in a row. It’s funny, until you remember that this chick is famous because she has a daughter.
