Looks like Amber Portwood is back jail.
It's not entirely clear why at this time, but a judge issued a warrant for her arrest today, and it was executed. The Teen Mom star was apprehended and booked.
The arrest may be related to Amber's most recent alleged probation violations, including a fight she got into at a restaurant last month or a new one entirely.
Amber Portwood is currently being booked at Madison County Jail in her home state of Indiana, where she's now expected to spend the night ... and the holidays.
She's due to face a judge on January 13 for violating probation. We're talking every single one of her probation terms. Think Lindsay Lohan style, but worse.
Amazingly, if she does spend Christmas behind bars, it will be the second consecutive year that's happened to Amber. Signs you may have some issues ...
UPDATE: Amber's brother Shawn tells E! News that his sister missed her most recent probation hearing and, as a result, authorities went to her house.
While there, they went through her purse and found some "old pills" that Amber said were from an earlier prescription ... which she couldn't produce proof of.
Therefore, she was jailed, release date TBA. Sheriff's deputies say it "will be up to the courts to decide" how long she stays there. Not looking good.
