Hef’s son, 21-year-old Marston Hefner has pleaded no contest to a domestic violence charge against his girlfriend.

Hefner was arrested last month after police were called to the Pasadena apartment he shared with 20-year-old Claire Sinclair (aka 2011 Playmate of the Year). Sinclair suffered minor injuries, moved out, and sought a restraining order against the young Hef.

“I’m looking forward to a public apology,” Sinclair told ABCNews.com last month. “I am against any sort of domestic violence so once that’s done, I’m ready to bury this and leave it in my past.”

As part of his sentencing, Hefner will need to undergo a year of domestic violence counseling.
