Green Day's Billie Joe Armstrong Wears BRAT Cap Amid Charli XCX Controversy at Coachella 2025

A playful feud between Charli XCX and Green Day emerged at Coachella 2025 after Charli wore a 'Miss Should Be Headliner' sash following her set, which many interpreted as a tongue-in-cheek jab at Green Day, who headlined the festival. In response, Green Day drummer Tré Cool donned a sash reading 'Actual Headliner,' while frontman Billie Joe Armstrong wore a neon green 'BRAT' cap—a nod to Charli's 2024 album—during their subsequent headline performance. The exchanges sparked lively debate online, with some Green Day fans taking offense and others viewing the interactions as lighthearted or supportive. Billie Joe Armstrong also made headlines for altering lyrics during their set to reference current political issues, including the Israel-Gaza conflict and Vice President J.D. Vance. The designer of Charli's sash clarified it was intended as a playful, unserious gesture. Overall, both artists seemed to diffuse tensions with mutual acknowledgments, and many fans called for an end to the supposed feud.
