Amber Portwood may be facing some serious legal trouble…serious even by the standards of Teen Mom stars.

Amber is required to submit to routine drug tests during her probation period, which shouldn’t be difficult considering she’s still on home confinement. But on Monday, it seems the trainwreck mom couldn’t pee for her daily test and her supposed bladder difficulties could land her in jail for five years.

Amber is due in court later today, at which time she’ll have to answer for the missed test or face serving out the five years she’s already been sentenced to. In the court’s eyes, not providing a sample is the same as failing a test, so Amber has some serious explaining to do.
