Mel Gibson has been charged with misdemeanour battery - assault - stemming from a January 2010 incident involving his then-girlfriend Oksana Grigorieva.
Los Angeles prosecutors charged the Academy Award-winner over the incident involving the Russian musician.
A person familiar with the case said Gibson will accept a plea deal.
Gibson is not expected to serve any time in jail.
His lawyer, Blair Berk, has said Gibson pursued a plea agreement with his children in mind. He has an infant daughter with Grigorieva.
