Marston Hefner is in hot water this morning after having been arrested on charges of domestic violence against girlfriend Claire Sinclair -- who just so happens to be one of his father Hugh Hefner's treasured Playmate of the Year gals.

Marston Hefner allegedly physically harmed Claire Sinclair on Sunday evening at their Pasadena, California home. Police were called to the location by family members of Sinclair's who reported Marston had attacked her.

TMZ reports Sinclair told cops Marston had punched her, kicked her in the stomach and then refused to let her leave the residence. According to law enforcement Marston admitted he and Claire, dating on-and-off since August 2010, had gotten into a fight but denied physically harming the 20-year-old, who was the 2011 Playmate of the Year.

Marston Hefner is the third child of Playboy mogul Hugh Hefner, born during his second marriage to Kimberly Conrad. The 21-year-old has a younger brother named Cooper and two half-siblings from Hugh's first marriage to Mildred Williams. The E! True Hollywood Story profile of Hugh Hefner noted the notorious Playboy Mansion had been transformed into a family-friendly homestead after Marston and Cooper's births. After Hugh and their mother separated she moved in to a house next door to the mansion.
