Naomi Campbell is joining the ranks of the many celebrities who are protesting censorship by celebrating the female body.

The supermodel uploaded a black and white topless image from her upcoming Taschen two-volume book of nude portraits by photographer Paolo Riversi, which were featured in Garage magazine.

Campbell wrote the hashtag #freethenipple in the photo's caption, which is a popular hashtag amongst social media users who are protesting the platform's history of censorship, particularly of women's bodies.

According to Instagram's user guidelines, it allows "photos of post-mastectomy scarring and women actively breastfeeding," however, many instances of policing is left up for users to report. While Instagram investigates these red flags, the rules can sometimes seem inconsistent on the outside.

While Campbell isn't the first celebrity to post a topless photo (other stars like Rihanna, Chelsea Handler and Chrissy Teigen have also recently joined the cause), her photo has yet to be removed from Instagram.

UPDATE: September 16, 2015, 5:20 p.m. EST: Instagram has officially deleted Campbell's post.
