Dani Mathers apologized months ago for posting a photo on social media of a nude 70-year-old woman in the shower area of a Los Angeles fitness center.

The 2015 Playboy Playmate of the Year was also banned from LA Fitness gyms, suspended indefinitely from her gig on a popular Los Angeles radio station and excoriated online, forcing her to go into social media hibernation.

Now it looks as if the 29-year-oldโ€™s punishment wonโ€™t end there.

Los Angeles City Attorney Mike Feuer filed criminal charges against Mathers on Friday. She faces a single misdemeanor count of invasion of privacy, Feuer said in a statement. If convicted, Mathers faces up to six months in jail and a $1,000 fine. Her arraignment is scheduled for Nov. 28.

โ€œBody shaming is humiliating, with often painful, long-term consequences,โ€ Feuer said. โ€œIt mocks and stigmatizes its victims, tearing down self-respect and perpetuating the harmful idea that our unique physical appearances should be compared to air-brushed notions of โ€˜perfect.โ€™

โ€œWhat really matters is our character and humanity. While body-shaming, in itself, is not a crime, there are circumstances in which invading oneโ€™s privacy to accomplish it can be. And we shouldnโ€™t tolerate that.โ€

Prosecutors accuse Mathers of surreptitiously taking the photo in the gymโ€™s shower area. They claim the lewd photograph of the naked 70-year-old was uploaded to Mathersโ€™ Snapchat account, where it ended up on her story. The caption: โ€œIf I canโ€™t unsee this then you canโ€™t either.โ€

โ€œIt pictured Mathers, sporting weight-lifting gloves and a Nike tank top, covering her mouth in false-shock,โ€ The Washington Post reported in July. โ€œWhat resulted was likely thousands looking at this womanโ€™s nude body, fat-shamed by a blond Playmate, on Mathersโ€™ public Snapchat.โ€

Mathersโ€™ act was illegal under California law. A section of the stateโ€™s penal code revised in 2014 said itโ€™s a misdemeanor to look โ€œwith the intent to invade the privacy of a personโ€ into places like a changing room, where a person has โ€œa reasonable expectation of privacy,โ€ with a camera. Under this law, itโ€™s illegal generally to distribute an image of the โ€œintimate body part or partsโ€ of another person โ€œwithout the consent of or knowledge of that other person.โ€

โ€œThere is no question that by her own caption that she intended to shame this woman and thatโ€™s the nub of the case,โ€ CBS News legal analyst Rikki Klieman said.

โ€œYou are not permitted in California to take photos in specific rooms where a person has a reasonable expectation of privacy โ€” theyโ€™re bathrooms, dressing rooms, changing rooms, tanning booths and rooms like that,โ€ Klieman added.

The 70-year-old woman photographed by Mathers is prepared to testify, CBS reported.

In addition to banning Mathers from all 800-plus of its gyms, LA Fitness notified the Los Angeles Police Department that Mathers photographed a member in its locker room. Thatโ€™s strictly prohibited, the Los Angeles Times reported.

โ€œHer behavior is appalling and puts every member at risk of losing their privacy,โ€ said Jill Greuling, the companyโ€™s executive vice president of operations.

โ€œOur written rules are very clear: Cellphone usage and photography are prohibited in the locker rooms,โ€ Greuling added. โ€œThis is not only our rule, but common decency.โ€

Los Angeles Police Capt. Andrew Neiman said the department received a report of โ€œillegal distributionโ€ of the image from the international gym chain. Detectives from the sexual assault section of LAPDโ€™s west division investigated.

Mathers apologized in July, then deleted her Twitter, Instagram and Snapchat, according to the New York Daily News.

Before she did, she recorded a Snapchat video in which she admitted sheโ€™d erred.

โ€œI know that body-shaming is wrong and thatโ€™s not what Iโ€™m about,โ€ Mathers said in the video, according to CBS. โ€œThat photo was supposed to be part of a personal conversation with a girlfriend and because I am new to Snapchat I really didnโ€™t realize I had posted it and thatโ€™s a huge mistake.โ€

Klieman told CBS that Mathersโ€™ excuse may not hold up in court.

โ€œFor heavenโ€™s sake, this elderly woman, we should be applauding her,โ€ the legal analyst said. โ€œSheโ€™s at the gym trying to make herself better. You can rest assured that this is a case that is really going to cause deterrence for not only the person who took the picture but also for others.โ€
