The mother of Levi Johnston has plead guilty to a drug charge stemming from her arrest in December.

Sherry Johnston -- onetime future mother-in-law of Bristol Palin, daughter of former Governor Sarah Palin -- entered a guilty plea to one count of possession with intent to deliver the prescription painkiller OxyContin, the Anchorage Daily News reports.

The 43-year-old grandmother to Tripp is scheduled to be sentenced in November. According to the ADN, her plea deal allowed her to get about half the minimum sentence because she had no previous drug-related convictions and was caught with a small amount of the drug. Her probation will continue for three years after her release from prison, her attorney told the paper.
