Hugh Hefner's son, Marston Hefner, has been officially charged with assault on girlfriend Playboy Playmate Claire Sinclair.
The charges stem from a domestic dispute incident two weeks ago that caused her to seek an emergency protective order against the 21-year-old.
Hefner was arrested after police was called to the couple's Pasadena apartment. He was taken into custody without incident and released on posting $20,000 bail.
However, Sinclair said that a "stressed out" Hefner came at her after a "really silly" argument they had.
"Initially, he kicked me and I went backwards, I fell," she said after the incident. "Then he punched me and grabbed me up, and I scratched him to defend myself. It was very shocking."
The two had been together for nearly two years.
Hugh Hefner had been hoping the two would work things out and no charges would be filed.
