The mother of Levi Johnston has been sentenced to three years in prison.
Sherry Johnston was sentenced Friday in Palmer, Alaska and Levi was in attendance. Johnston pleaded guilty in August to one count of possession with intent to deliver the painkiller OxyContin. Five other felony counts were dropped in the deal, which called for a five-year prison sentence with two years suspended.
The Anchorage Daily News reports that she will serve her sentence at Alaska's only female prison.
Johnston is the grandmother of Levi and Bristol Palin's son, Tripp.
