Billie Eilish’s “When the Party’s Over” soundtracks a new Kamala Harris ad that targets the dangers of not having reproductive care under a Donald Trump presidency.

In the one-minute clip, reproductive freed activist Hadley Duvall tells a devastating story of how she became pregnant after her stepfather raped her when she was just 12 years old. While she was able to get to have options like abortion for her pregnancy, Duvall warned that due to Roe v. Wade having been revoked, young women can no longer get the care they need, even when the pregnancy is die to incest or rape.

Eilish’s recognizable chorus is heard as Harris approves the message.

Oh my goodness. This new Kamala Harris ad is so powerful. Hadley Duvall tells how her stepfather raped her when she was 12 & then she became pregnant. But girls now can no longer access the care she got because of Trump. Billie Eilish closes the ad. Watch. pic.twitter.com/sSjB72tQ8A

Earlier in the day, Eilish and her brother Finneas voiced their support for Harris. “We are voting for Kamala Harris and Tim Walz because they are fighting to protect our reproductive freedom, our planet and our democracy,” the “Bad Guy” singer says in a clip posted to social media.

“We can’t let extremists control our lives, our freedoms and our future,” Finneas continues. “The only way to stop them and the dangerous Project 2025 agenda is to vote and elect Kamala Harris.”

The pair also shared a link where fans can check their registration status ahead of election day on Nov. 5. “Vote like your life depends on it,” Eilish adds in the clip. “Because it does.”
