Hugh Hefner's son Marston has reportedly pleaded no contest to corporal injury to a spouse or cohabitant.
The Associated Press reports that the 21-year-old is expected to undergo a year of domestic violence counseling.
Last month, police were called to Marston's Pasadena home where he was living with model girlfriend Claire Sinclair, 20. Sinclair, the 2011 Playmate of the Year, was found to have minor injuries. Marston was then arrested and Sinclair filed a restraining order against him.
