Law enforcement sources say Portwood got popped on December 16 for possession of a controlled substance. It's unclear what exactly the substance was.
She also failed to provide mandatory urine drug screening results on December 16 and December 19. Not a smart move when you're on probation already.
Amber Portwood
That's not even all. Amber Portwood is on the hook for various other alleged probation violations, including failure to complete anger management class.
A judge recently ordered her to set up a college fund for her young daughter, Leah. You can probably guess whether or not that's happened.
Spoiler: It has not.
As such, Amber was ordered to remain in custody until her hearing in late January. At that point, the Teen Mom's longer-term fate will be determined.
SIDE NOTE: This is her second straight Christmas in jail. Wow.
