"We hate you!" Olivia Rodrigo and Lily Allen teamed up at Glastonbury Festival over the weekend to protest Friday's Supreme Court ruling that takes away Americans' constitutional right to abortion. On stage, Rodrigo told the thousands watching she is "devastated and terrified" about the Supreme Court's ruling. "This song goes out to the justices: Samuel Alito, Clarence Thomas, Neil Gorsuch, Amy Coney Barrett, Brett Kavanaugh," she said. "We hate you!" She then was joined by Allen in a surprise appearance to perform Allen's 2009 hit "(Expletive) You." The single was a reaction to political adversaries in the U.S. and U.K. when it debuted. Other singers at Glastonbury used their platforms to protest the Supreme Court's decision. Billie Eilish, Glastonbury's Friday headliner, dedicated her song "Your Power" to SCOTUS judges who voted to overturn Roe v. Wade. And Phoebe Bridgers led an explicit chant against the "irrelevant" Supreme Court Friday for "telling us what to do with our (expletive) bodies." 🔗 Read more + see more photos from #Glastonbury at our link in bio. 📸 Joseph Okpako, WireImage
