According to Page Six, the 50-year-old model posted a picture on Instagram on Saturday (local time) featuring herself in the buff while exploring a subway station.
In one photo, she's seen sitting in a chair while clutching a Valentino handbag.
In another photo, she is seen waiting on the subway platform barefoot, holding a different Valentino purse.
The third snap shows the stunner with one more Valentino bag in her lap, tagging the fashion house in all three posts.
The 'Making the cut' judge also mentioned that the photos went "unpublished," meaning there's no telling whether the shoot took place before or after the city-wide spread of COVID-19.
The images shocked fans online, not only because of her state of undress but because Campbell has been particularly cautious when it comes to avoiding the Covid-19 virus. She was seen wearing a full hazmat suit during a March flight from Los Angeles to New York.
"It's not a funny time, it's not a humorous time, I'm not doing this for laughs," she insisted. "This is how I feel comfortable travelling if I have to travel; I'm trying to keep it to a minimum."
