King Princess can sum up her new single "Cursed" with three words: "Toxic Friendship Anthem." The 23-year-old pop star goes deep on the exhilarating track on the latest episode of Rolling Stone's "The Breakdown." The video features Straus at Mission Sound, her father's studio in Williamsburg, Brooklyn. She's wearing the same Fiona Apple shirt she wore during her interview for Rolling Stone's latest digital cover story — a stylish item that she says was a gift from a fan.
