As seen on: Teen Mom (2009-2012)

The fact that Amber Portwood is the only reality star on this list currently serving a prison sentence should tell you something.

During her time on Teen Mom, she was involved with Gary, and their relationship was without a doubt one of the most destructive, abusive relationships to ever be seen on television—and the most violent fights, both verbal and physical, were often in the presence of their young daughter, Leah. Watching real-life trauama is what shows like Teen Mom  specialize in, but when that manifests itself as physical violence, especially in front of a young child, it’s time to turn the cameras off.

As we previously mentioned, Portwood is no longer living the life of a reality television star, as she’s currently serving a five-year prison sentence for drug charges from 2011.
