Fortnite swaps Ironmouse's Jam Track cover after a Gemini watermark is spotted

Fortnite has replaced the cover art on Ironmouse's "Meow" Jam Track after players noticed it carried the white star watermark that Google's Gemini adds to images it generates. The mark sat in the bottom right corner of the artwork for her album Club Ironmouse, and the same picture was in use on Apple Music and Spotify. A Reddit post raised it; the border's own stars made it easy to miss.

“I had no idea. Thanks for bringing it to my attention. My team has contacted the people in charge of this particular release and demanded it to be changed.”

"Meow" is credited to Ironmouse, Sleeping Forest and HalaCG, and arrived in Fortnite as a Jam Track on 19 September. Club Ironmouse is her first full-length album, thirteen electronic tracks released in January 2026. Within days of the complaints, the cover was changed on all three services to a version with a different background and no watermark.

Ironmouse is a prominent VTuber and an outspoken critic of generative AI, which made the discovery sting. Replying to a fan, she said she had no idea and that her team had told those in charge of the release to get it changed. In June she had dropped a sponsored stream for Neverness to Everness because of that game's use of AI.

Responsibility is being passed along the chain. Epic said the artist supplied the art, identical to what went to every platform, and that it swapped it once a new version arrived. Trap Nation, the promoter that distributed the track, said the artwork was never meant to be final, that Ironmouse did not know AI had been used, and apologised. The artist who made the Club Ironmouse logo said they produced only the logo, in Procreate and Illustrator, and not the album cover.

Aftermath argues Epic should have caught the mark and puts the main fault on the distributor. It notes that Epic itself uses AI in its pipeline, and that some fans had already called the Fortnite collaboration hypocritical when it was announced. It asked Ironmouse, Epic and Trap Nation how the image got through and how they will prevent a repeat, and had no replies at publication.
