Los Angeles police have charged Playboy model Dani Mathers over a "body-shaming" image she took of an older woman in a gym locker room.
The picture of the naked 70-year-old was taken in LA Fitness in July without her consent and posted on social media.
She uploaded the photo to Snapchat alongside one of herself and the caption: "If I can't unsee this then you can't either".
Ms Mathers faces a charge of invasion of privacy.
She could face up to six months in jail and a $1,000 £800 fine if convicted.
Ms Mathers, 29, apologised soon after uploading the image, saying she thought her Snapchat post had been a private conversation and acknowledging that "body-shaming" is wrong.
