The oldest son of PLAYBOY founder, Hugh Hefner, Marston Hefner, 21, was arrested for suspected domestic violence after a fight with his 20 year old girlfriend, Claire Sinclair, the 2011 Playmate Of The Year. He was booked on assault charges, but was able to get himself released from jail after posting a $20,000 bond. Sinclair is seeking a temporary restraining order against Marston, although she doesn’t want to press charges against him. Oh, what a lovely Norman Rockwell moment this is.

Marston is the older of two sons that Hugh Hefner had with his former lover, Kimberly Conrad.

Today, TMZ reports that Claire Sinclair cannot drop charges against Marston Hefner, because the state does the prosecution of domestic violence crimes. Sinclair claims that Marston has anger control issues and needs professional counseling.

The baby-faced Sinclair has sported at least one big bruise on an arm after the claimed assault took place.
