The woman, whose nude body in an LA Fitness locker room was beamed to the world by the 29-year-old model with the words "If I can't unsee this then you can't either", is reportedly willing to testify after police recommended criminal prosecution, reports TMZ.

If charged with the crime of Dissemination of Private Images, the 2015 Playboy Playmate of the Year faces up to six months in jail.

According to the news site, LA police are keen to make an example of the model's public body shaming and contravention of the gym's strict rules around the prohibition of photography and mobile phone use in its locker rooms.

At the time, the gym chain immediately banned the model from its 800 branches and notified the police of the incident.

"Her behaviour is appalling and puts every member at risk of losing their privacy," said Jill Greuling, the company's executive vice president of operations.

The Washington Post reported that the act was illegal under Californian law, explaining that a 2014 revision of its Penal Code stated that it is a misdemeanour to look "with the intent to invade the privacy of a person" into places such as a changing room, where a person has "a reasonable expectation of privacy," with a camera. Under this law, it's illegal generally to distribute an image of the "intimate body part or parts" of another person "without the consent of or knowledge of that other person."

According to TMZ, the model has hired lawyer Tom Mesereau, who famously represented Michael Jackson in court.

Besides the legal ramifications, Mathers found herself of the receiving end of a barrage of outraged social media users after the spiteful and badly calculated post.

And that was before they knew the victim of the millennial model was in her 70s.
