Green Day drummer Tré Cool wore sash made of toilet paper which read 'Actual Headliner' at Coachella to mock singer Charli XCX. Green Day headlined Coachella in California, while Charli XCX performed earlier and wore 'Miss Should Be Headliner' sash to afterparty. Further, Green Day frontman Billie Joe Armstrong closed the show wearing 'Brat' hat, in reference to Charli's album.
