Fans compared the necklace design to that of the Nazi's Black Sun image.

Shakira found herself in the midst of controversy after fans called out the singer for selling a tour merchandise necklace resembling a Nazi symbol.

The necklace, a featured product for the singer’s El Dorado tour, was first called out by German publication Bento, which noted a resemblance between the pendant and the Nazi Black Sun symbol. The Black Sun was first used in a mosaic at the Wewelsburg Castle in Germany, which served as a home base for the SS party and Adolf Hitler's close associate, Heinrich Himmler.

Fans also questioned why the singer would sell a design without having researched the symbol.

So Shakira most likely accidentally put a nazi symbol on her tour merch and didn’t know it lmao pic.twitter.com/HRjP41owbO

Whenever, whatever.
Do you even research the symbols you use for your World Tour merch? @shakira

With the image circulating online, concert producer Live Nation took to Twitter to address the backlash, explaining that the necklace design was “based on Pre-Columbian imagery.”
