Amber Portwood, one of the stars of MTV's "Teen Mom," has been sentenced to five years in prison after she decided to leave court-mandated drug-rehab program.
Portwood, 22, pleaded guilty in February to felony possession of a controlled substance and admitted to violating her probation; she avoided prison time by entering the program, The Associated Press reported.
Portwood quit the program on Tuesday and was slapped with her original five year sentence. E! News reported that she will be given credit for the 120 days she served in the program.
In 2010, the "Teen Mom" star received probation after pleading guilty to a domestic battery charges from an incident with Gary Shirley -the father of her now 3-year-old daughter - which aired on the show. Her daughter, Leah, is in the custody of Shirley.
