Social media users are accusing the Baywatch star, 52, of cultural appropriation after she tweeted two photos of herself wearing nothing but white underwear and a traditional Native American headdress on Halloween.

In the first shot, a topless Anderson can be seen covered in white paint, holding the large feather piece over her shoulder.

The controversial costume received instant backlash, with many social media users calling Anderson’s post racist and insensitive.

Anderson — who’s participated in animal right’s protests and starred in several PETA ad campaigns — was also called out for wearing bird feathers.

It’s barbaric and unsustainable ..to beat baby seals – crush there skulls for a 2$ pelt that there is no market for.

Speaking with NPR last week, Henu Josephine Tarrant (an artist and performer of the Ho-Chunk, Hopi and Rappahannock tribes) explained that Native American Halloween costumes are problematic because they inaccurately portray modern Indigenous people.
