amberportwood230.jpgMuch maligned Teen Mom star Amber Portwood has been sentenced to five years in prison after failing to complete her drug rehab program.

According to multiple reports, a judge reimposed her five year sentence on Tuesday when the 22-year-old reality star decided to opt for prison after having quit after three months into her rehab assignment.

Portwood was sentenced to three years in prison for possessing prescription drugs without a prescription and an additional two years for violating probation. Instead of her sentence, she struck a plea agreement which allowed her to skip jail upon completion.

Portwood can still avoid serving the entire five years of her sentence depending on "good behavior," where she can reduce her time by up to four years, or one-third of a prisoner's sentence, according to Indiana's prison policy.

There has been no word on when her sentence will begin. Her 3-year-old daughter Leah is in the custody of Gary Shirley, the father.
