In the photo she shared, the 49-year-old is seen completely naked with just a thin gold chain around her waist.
The photo, which is also showcased in Vogue, is captioned “first drop of golden hour”.
The model told the fashion magazine that she hasn’t felt comfortable in her body until recently.
She said: “Whenever I did something like lingerie pictures, I continued to feel incredibly self-conscious.”
Even in my day-to-day life, if I was in the street wearing tight jeans or leggings, I’d always be sure to tie a cardigan around my waist so that I didn’t feel exposed.”
The supermodel, who named as the new face of Nars late last year, believes that her confidence has “come with age”.
“It’s taken me a long time to feel right in my body and has really only happened over the past few years.”
As well as feeling more confident about the way she looks, Naomi Campbell says she feels more relaxed about taking days off if she’s not feeling 100 per cent.
“I know my limits: I know when I have to take time out.” She said in the July issue of Vogue.
“I’ve learned not to feel guilty about staying in bed when I’ve spent several weeks at work; I now know how to lie on the beach and just let the day go by.”
She shared one other image from her shoot on her Instagram, shot on location in Malindi, Kenya.
Fans of the supermodel rushed to praise the “iconic model.”
“I thought this was a throwback.” One Instagram comment read.
Another said: “She will forever be a timeless beauty.”
