Court papers filed Friday in federal court in Manhattan say the magazine violated Playboy's exclusive right to publish the pictures taken by fashion photographers Mert Alas and Marcos Piggott for the publication's 60th anniversary issue.
The suit alleges Harper's posted on its website a clothed photo of the 40-year-old supermodel from the Playboy shoot but added a hyperlink that took readers to another website showing the nude and partially nude photo spread.
The lawsuit seeks $150,000 per photo infringed.
Representatives for Harper's Bazaar didn't immediately return messages Friday.
