Global superstar Billie Eilish returns to Reading Festival, this time to headline the Main Stage East, where on a sunny afternoon in 2019, she drew arguably the biggest crowd of the weekend. At just 21, she is the youngest solo artist to date to headline the event. The LA alt-pop sensation has built a hugely dedicated fanbase, has two UK number one albums under her belt, When We All Fall Asleep, Where Do We Go? and Happier Than Ever, and recently joined a stellar cast on the Barbie movie soundtrack with the hit What Was I Made For?
