Gwen Stefani is coming under fire for a Christmas partnership with a prayer app that appears to have ties to right-wing causes and policies.

The Grammy winner kicked off December by inviting her fans to join her and “millions of others” in a daily prayer challenge through the Hallow app.

“It is important this Christmas season to spend time in prayer,” Stefani said in a video posted on December 1. “That’s what Christmas is about: letting God into our hearts and letting Jesus bring us his peace.”

The publication was marked as part of a paid partnership with Hallow, which offers access to a catalog of Catholic prayers, meditations, audio-guided Bible stories and worship music for $70 a year.

Stefani’s endorsement caught the attention of activist and influencer Matt Bernstein, who dug deep into the app and criticized the pop star in a video posted to social media on Monday.

“It’s the most wonderful time of the year, aka when Gwen Stefani becomes complicit with the right-wing anti-abortion, pay-per-prayer app Hallow,” he said, describing the download as a “religious scam.”

Bernstein highlighted the variety of anti-abortion prayers on the app, including one that specifically called for blessing women “pregnant by acts of rape and incest” who are considering abortion.

To illustrate Hallow’s ties to conservative politics, he also noted that Vice President JD Vance and conservative mega-donor Peter Thiel were early investors in the app.

Stefani has yet to publicly react to the backlash and her representatives did not respond to News’s request for comment.

Although the singer largely keeps her personal politics private, she came under fire in March for publicly praising far-right pundit Tucker Carlson’s interview with actor Jonathan Roumie, who plays Jesus Christ in the Netflix Bible series “The Chosen.”
