Ellise Shafer Dua Lipa lit up the Glastonbury Festival on Friday night, not just with the many fireworks that went off during her set. The pop star surprised the crowd by bringing out Kevin Parker of Tame Impala fame — who produced her latest album, “Radical Optimism” — for a duet of the band’s hit “The Less I Know the Better.” Before bringing out Parker, Lipa played a mix of new songs and her biggest hits, including “Training Season,” “One Kiss” and “Levitating.” Addressing the crowd, Lipa said she had manifested this moment. “I have written this moment down, I’ve wished for it, I’ve dreamt it,” she said.
