The pop star Ariana Grande is suing Forever 21, claiming that the fashion retailer sought to trick customers into thinking Grande endorsed its brand by posting photos of her on its social media accounts and using a model who looked “strikingly similar” to her.

The lawsuit, filed Monday in Federal District Court in Los Angeles, mostly revolves around imagery from Grande’s music video “7 Rings,” which depicts a pink-tinged house party for a bejeweled Grande and her friends. The lawsuit takes issue with posts from Forever 21’s Instagram account that include snapshots from “7 Rings” and advertisements in which the “look-alike model” — a brunette with a slicked back high ponytail — is dressed similarly to Grande in the video.

In one post on Forever 21’s Instagram account, the model wore a hairpiece with two pink puff balls. The caption echoed lyrics from “7 Rings” (“Gee thanks, just bought it”) and asked viewers to “shop our favorite trend.” In another post, the model wore camouflage capris and pink stilettos, urging users to “swipe up to shop.”
