The Snapchat post included an insulting comment about the woman's body.

The city attorney's office said Friday that Dani Mathers faces a misdemeanor count of invasion of privacy. She is scheduled to be arraigned Nov. 28. It wasn't immediately known if Mathers has an attorney.

The 29-year-old Mathers faced widespread criticism after she shared the photo in July with the caption: “If I can't unsee this then you can't either.” She later apologized and deleted her social media accounts.

The gym, LA Fitness, reported the posting to police and revoked Mathers' membership.

Inspiring body positivity quotes Danielle Brooks "Sometimes I don't like what I see, but I have the power to change the way in which I relate to my body both physically and mentally." Inspiring body positivity quotes Iskra Lawrence "Stop comparing yourself to anybody else. The [pictures of] movie stars, even the Disney characters, that’s not real. That’s not attainable. You can’t be anybody else. You are you. You can’t be them. So you really just have to start embracing yourself and accepting so-called flaws that society has given the name ‘flaws’. It’s just our body, our patchwork quilt.” Inspiring body positivity quotes Beyoncé "The most alluring thing a woman can have is confidence."

I'm proud of that."

If convicted, Mathers could face up to six months in jail and a $1,000 fine, according to City News Service.

Detectives began investigating after the LAPD received a report of “illegal distribution” of the image, police Capt. Andrew Neiman said after the photo became public.

“Her behavior is appalling and puts every member at risk of losing their privacy,” Jill Greuling, an LA Fitness executive vice president, said at the time.

The person in the photo was identified only as a 70-year-old woman and it was not clear if she knew she was being photographed.

Mathers said in July that she accidentally posted the photo publicly.

“That was absolutely wrong and not what I meant to do,” she said in an online video. “I know that body-shaming is wrong. That is not the type of person I am.”

Mathers was Playboy's Miss May in 2014.
