Amber Portwood is one of four young mothers featured on the popular MTV reality series Teen Mom. In 2009, Portwood began her reality television run when she appeared in an episode of 16 & Pregnant during Season 1, which followed Portwood and her then-boyfriend, Gary Shirley, as they welcomed their first child, Leah, as teens. Years later, Portwood was sentenced to a five-year prison term following a probation violation after being found guilty of assaulting Shirley months prior. Upon her release, Portwood, who served just 17 months of her term, began filming the fifth season of Teen Mom. During the show, she became engaged to Matthew Baier.
