Green Day, Camila Cabello, Lil Nas X, Steve Aoki and so many more stormed Las Vegas on Friday night (September 20) for the 2019 iHeartRadio Music Festival. As it does every event, the annual music affair brought together music fans from all walks of life to one room and it was quite the sight to see. From Green Day's epic return to the Festival stage to Cage the Elephant front-man Matt Shultz's strip-down, the evening aligned all the superstar acts and we have a round-up of some of the hottest photos from the big night!
