"Teen Mom" Amber Portwood has been thrown back in jail -- this after a judge issued a warrant for her arrest today, TMZ has learned.
It's unclear why the judge issued the warrant -- whether it's related to Amber's most recent alleged probation violations, including a fight Amber got into at a restaurant last month ... or a new one entirely.
Amber is currently being booked at Madison County Jail in Indiana -- where she's now expected to spend the holidays.
She's due to face a judge on January 13. The booking photo was first obtained by FOX59 in Indianapolis.
