PASADENA, CALIF. (AP) - Hugh Hefner’s 21-year-old son has pleaded no contest to a misdemeanor domestic violence charge stemming from an incident with his girlfriend at their Pasadena home.

Assistant Pasadena City Prosecutor Chris Blankenhorn tells City News Service that Marston Hefner pleaded no contest Tuesday to corporal injury to a spouse or cohabitant.

Marston Hefner was arrested last month after police were called to the apartment he shared with 20-year-old Claire Sinclair, the 2011 Playmate of the Year. Sinclair had minor injuries and sought a restraining order against the younger Hefner the next day.

Blankenhorn says Marston Hefner is expected to undergo a year of domestic violence counseling. He also is ordered to stay away from Sinclair for three years.
