Here's Why Nobody Should Be Confused Over Gwen Stefani Endorsing a Catholic Praying App

Gwen Stefani has left fans stunned by trading her signature glam for a more modest style in a new video promoting the prayer and meditation app, Hallow.

The Voice coach donned a plaid dress as she decorated a Christmas tree and spoke about the true meaning of the season.

"It's the time we get to celebrate the birth of our Lord," Gwen shared in the clip.

In her latest project, Stefani partnered with Hallow for its 25-day Advent Pray Challenge leading up to Christmas.

"Join me and millions of Christians around the world as we celebrate the truth that God so loved the world, He gave us His only Son," she encouraged. "Download Hallow and pray with me every day. God bless!"
