Amber Portwood

Teen Mom star Amber Portwood has been sentenced to five years in prison for the second time in six months.

Portwood was originally sentenced in January for drug possession, but the judge decided to offer her a second chance. In exchange for doing time, Portwood could complete a drug rehabilitation program instead.

As TMZ reports, Portwood gave up on the program and, in a surprising turn of events, asked the judge to reinstate her sentence. On Tuesday, the reality star got her wish when the judge enforced the terms of Portwood's original plea agreement.

Portwood will head to the Indiana Department of Corrections therapeutic community program and will be given credit for time served in jail.

This isn't Portwood's first run-in with the law. While filming Teen Mom, Portwood was arrested for domestic violence in 2010 against her baby's father, Gary.
