Dozens of entertainers and musical artists — including big names like Ariana Grande, Billie Eilish, Megan Thee Stallion, and more — have signed on to an ad from Planned Parenthood declaring they are being "robbed of our power" by losing the right to kill their unborn children.

The full-page ad ran in the New York Times Friday days after a leaked Supreme Court draft majority opinion for Dobbs vs. Jackson Women's Health Organization indicated the court will uphold Mississippi's 15-week abortion ban and overrule its landmark Roe v. Wade decision. This action by the court would end the constitutional right to kill unwanted children before they are born and activate so-called trigger laws in 26 states that would ban or restrict abortion access.

In response, Planned Parenthood, the nation's number one abortion provider, has launched a "Bans Off Our Bodies" campaign to oppose the Supreme Court's expected decision and pro-life laws. The New York Times ad is part of that campaign.

"Our power to plan our own futures and control our own bodies depends on our ability to access sexual and reproductive health care, including abortion," the ad states.

"We are Artists. Creators. Storytellers. We are the new generation stepping into our power. Now we are being robbed of our power. We will not go back — and we will not back down," the signatories declare.

In addition to those mentioned, the ad was signed by numerous celebrities including Kendall Jenner, Selena Gomez, Olivia Rodrigo, Shawn Mendes, Camila Cabello, Demi Lovato, Halsey, Hailey Bieber, Camila Mendes, Lili Reinhart, Madelaine Petsch, Karlie Kloss, Ariana DeBose, Madelyn Cline, Hailee Steinfeld, Dove Cameron, FINNEAS, Hayley Kiyoko, Madison Beer, Phoebe Bridgers, Joey King, Peyton List, Lauren Jauregui, Jenna Ortega, Storm Reid, Tinashe, Meghan Trainor, Tommy Dorfman, Melanie Martinez, Liza Koshy, and Maia Mitchell.

"These young artists are encouraging their fans to join them in speaking out in support of the right to access sexual and reproductive health care, including abortion," Planned Parenthood said in a statement.

"What we see in young people from all walks of life is that they aren’t backing down — not today, not ever. Like the artists who signed on to this ad, their resolve to keep bans off their bodies is a source of hope during a dark time, and we are determined to keep fighting alongside them, for them," she added.
