Playboy founder Hugh Hefner's 21-year-old son has been sentenced to a 52-week domestic violence program after allegedly beating his Playmate girlfriend Claire Sinclair last month. Marston Hefner was charged with corporal injury after allegedly attacking Sinclair, giving her bruises and damaging her laptop. Vandalism charges for the laptop were dismissed, but the judge added that Hefner should stay away from Sinclair.
