Green Day Challenges Charli XCX's Headliner Claims at Coachella

A playful rivalry emerged between Green Day and Charli XCX at Coachella 2025 after Charli wore a 'Miss Should Be Headliner' sash, sparking online debate about her festival billing beneath the legendary punk band. Green Day responded in good humor, with drummer Tré Cool donning a homemade ‘Actual Headliner’ sash and frontman Billie Joe Armstrong wearing a neon green 'Brat' hat—an apparent nod to Charli’s album branding—during their headlining set. Fans from both camps debated the appropriateness of Charli's gesture, but most agreed the antics were lighthearted and part of the festival's showmanship. Green Day further engaged fans by inviting one on stage to play guitar during a surprise performance of 'Knowledge,' a rare deep cut. Despite the initial controversy, both acts and their supporters seemed to embrace the banter, with many acknowledging the mutual respect and entertainment value. The episode highlighted both Charli's breakout year and Green Day's enduring headliner status, reinforcing their respective places in contemporary music culture.
