Die Antwoord have a bone to pick with Suicide Squad director David Ayer.
The South African rap duo have accused Ayer of "jockin" their style without their permission, and ripping off their iconic look for the imagery of Suicide Squad.
In an Instagram post, singer Yolandi Visser wrote that the pair noticed "all the little tiny details [Ayer] nibbled".
She also claimed that the film's stars Jared Leto and Cara Delevingne had given them the heads up, writing: "Cara and Jared told us how much you were talking about us on set, but you never asked our permission to rip us off."
Delevingne previously appeared in Die Antwoord's music video for their song Ugly Boy.
Along with the comments, Visser posted a video which compared Die Antwoord's look to scenes used in Suicide Squad, including a picture of Die Antwoord member Watkin Tudor Jones, also known as Ninja, next to a photo of Jared Leto's Joker.
In it, both possess body tattoos and slicked back hair.
In another photo Visser wears three watches, similar to the way Margot Robbie's Harley Quinn wears multiple watches.
They also slammed Ayer for "pretending to be down", and suggested he start a crew of fakers and "ask Kanye [West] if he wants to join".
David Ayer has yet to respond to Die Antwoord's claims.
