Amber Portwood is back behind bars. Authorities claim the Teen Mom star lied about a medical condition in order to get out of a mandated drug test.

Amber didn’t show up drug court and then claimed that she was on doctor-ordered bed rest for 2-3 weeks following gall bladder surgery. When Amber’s probation officer called her doctor to corroborate the story and found out that it was a fabrication, he ordered that she be returned to jail immediately. Amber is expected to remain locked up for at least two weeks while the court decides her future.

Amber served two months behind bars earlier this year for a probation violation. She could face several years in prison for her latest stunt.
