Charli proves that 'Brat' is forever with Saturday night headlining set. How to bring Charli xcx’ s one-woman show – a triumph of emotive pop hedonism and discomfiting intimacy – to a sprawling, city-sized Worthy Farm? It was never going to be an easy task.

Gracie Abrams — on Worthy Farm this weekend as a performer, also — was selected as the Grammy winner's "Apple" girl on Saturday night.

Charli XCX performed on the festival’s Other Stage at the same time as Neil Young on the Pyramid Stage and Doechii on the West Holts Stage. Despite facing this considerable competition for fans’ attention, she still managed to draw a huge crowd, and there was a sense that she was Saturday night’s headliner in all but name.
