Kendrick Lamar and SZA’s collaborative “All the Stars” video has been accused of using artwork from a British-Liberian artist without permission, according to The New York Times. (The song appears on the Black Panther soundtrack that Kendrick and TDE’s Anthony Tiffith curated and produced.) Lina Iris Viktor said representatives from Marvel contacted her in November 2016 and December 2017 about using her artwork in the film, but she ultimately declined their offers, the Times reports. Yet, images similar to her “Constellations” series appear in Kendrick’s music video. See below at the 2:59 mark.

Viktor’s lawyer, Christopher Robinson, sent Tiffith a letter on Saturday, alerting him to the copyright violation, the Times reports. Viktor told the Times, “It’s an ethical issue, because what the whole film purports is that it’s about black empowerment, African excellence—that’s the whole concept of the story. And at the same time they’re stealing from African artists.” She is seeking a public apology and a license fee, according to the Times. Pitchfork has reached out to representatives for comments.

Earlier today, Kendrick thanked everyone who worked with him on the Black Panther soundtrack. “The concept of producing and composing a project other than my own has always been ideal,” he wrote.
