Hugh Hefner’s 21-year-old son, Marston, pled no contest to a charge of domestic violence. Apparently he got into an altercation with his playmate girlfriend Claire Sinclair.

Marston supposedly punched Claire, kicked her in the stomach, and wouldn’t let her leave their home.

According to Pasadena assistant city prosecutor, Chris Blankenhorn, Marston is scheduled to be sentenced on June 12 in Pasadena after entering his plea on Tuesday to the charge of corporal injury to a cohabitant.

Hefner is expected to receive no jail time. Instead, he will have to pay for and attend one year of domestic violence counseling and refrain from any contact with Sinclair for three years.

Claire was named the 2011 “Playmate of the Year.”

Hugh Hefner told Fox News that Claire’s style reminded him of Bettie Page, a popular 1950s pinup model who was also Playboy Magazine’s Miss January cover model in 1955.

In the following YouTube video Claire said her relationship with Marston was going well, “But said it was very tumultuous, to be honest — we’re very good friends when it comes down to it. I am blessed to have someone who is so supportive.

She may have even implied that Marston was very possessive, “Marston travels out to see me no matter what I am doing.”

When she was asked if wedding bells were in the future she said, “Hell No! Hell No!”

The couple have been dating off and on since 2010.

During an interview with Maximo TV in November, Claire dominated Marston and hardly let him answer questions from the reporter.

Claire said she wouldn’t press charges on her boyfriend if he apologized publicly and received psychiatric treatment.

Hopefully Claire will move on from this unfortunate experience and have a safe and wonderful life.
