Olivia Rodrigo, Lily Allen dedicate pointed song to SCOTUS at Glastonbury after Roe v. Wade ruling

Olivia Rodrigo, Lily Allen, Billie Eilish and more singers used their platforms at Glastonbury Festival over the weekend to protest Friday's Supreme Court ruling that takes away Americans' constitutional right to abortion.

The watershed decision overturned Roe v. Wade and erased reproductive rights in place for nearly five decades.

In the court's most closely watched and controversial case in years, a majority of the justices held that the right to end a pregnancy was not found in the text of the Constitution nor the nation's history.

Taking the stage on Saturday at the U.K. festival in southwest England, Rodrigo told the thousands watching she is "devastated and terrified."

Celebrities react to Roe v. Wade overturn:Rita Moreno 'frightened' over SCOTUS ruling, recalls her abortion "So many women and so many girls are going to die because of this," she added.

Introducing her next song, Rodrigo said, "This song goes out to the justices: Samuel Alito, Clarence Thomas, Neil Gorsuch, Amy Coney Barrett, Brett Kavanaugh. 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.

'I feel different now':Billie Eilish on wanting kids, battling low self-esteem Eilish, Glastonbury's Friday headliner, dedicated her song "Your Power" to SCOTUS judges who voted to overturn Roe v. Wade.

"The song we’re about to do is, I think, one of the favorites that we’ve written and it’s about the concept of power and how we need to always remember how not to abuse it,” she said. “And today is a really, really dark day for women in the U.S. I’m just going to say that as I cannot bear to think about it any longer in this moment.”

Meanwhile, Phoebe Bridgers led an explicit chant against the "irrelevant" Supreme Court Friday for "telling us what to do with our (expletive) bodies."

Rodrigo, Bridgers and Eilish are among more than 150 celebrities and influencers who signed a petition last month to show they don't support the high court overturning Roe v. Wade after a draft opinion from the Supreme Court leaked.
