They’ll be celebrating their four year wedding anniversary in three months.  

And Gwen Stefani previously revealed how her faith has benefitted her marriage to Blake Shelton.

Stefani, a devout Catholic, revealed how a higher power played a role in her relationship as she chatted with Drew Barrymore on a November episode of her eponymous talk show.

‘What’s the best advice you’ve ever received about love?’ Drew, 50, asked the No Doubt songstress, 55.

‘Best advice would probably be, make sure you have a third party,’ Gwen said.

She pointed her finger upwards, indicating God.

The interview came shortly before Gwen divided fans by promoting the Catholic prayer app Hallow. 

Gwen partnered with the popular prayer and meditation app to encourage people to pray over the holiday season last year.

‘Christmas season has always been my favorite time of the year. It’s the season that we get to celebrate the birth of our Lord,’ she says in a promotional video.

‘Join me and millions of other Christians around the world as we celebrate together the truth that God so loved the world that he gave us his only son.

While a lot fans have supported Gwen’s public embrace of her faith, others criticized the Hollaback Girl hitmaker for the religious venture.

‘Trad wife transformation complete,’ wrote one, while another commented, ‘What the hell is this!’

‘I’m just going to tell myself this is AI and continue with my life,’ wrote a third.

A fourth added, ‘Gwen, I’ve loved you since I was eight years old back in the Tragic Kingdom days. I understand your faith is important to you but this is seriously cringe.’ 

‘Best advice would probably be, make sure you have a third party,’ Gwen said before pointing to the sky in a reference to God

Stefani and her husband have been married since July 2021

Another commented, ‘Who is this and what have you done with the real Gwen?!! This cannot be real. Not only she just makes music to match her husband’s but now she seems like such a Republican.’

Despite the backlash, plenty of fans jumped in to defend Gwen and pointed out that she’s always been open about her religious convictions.

‘Gwen has ALWAYS been a religious person. This is nothing new. She’s just more vocal about it now,’ wrote one.

‘Y’all do know Catholics are Christians, right? Stefani is Italian. What Italians do y’all know who aren’t Catholic??’ added a second.

A third wrote, ‘I really feel the need to defend her here! Gwen has always been open about her faith. She was raised Catholic and if anything her faith is part of why her and Blake fell for each other.’ 

She posted another Hallow promotional video last month and also re-tweeted Tucker Carlson’s interview with Jonathan Roumie, who stars as Jesus in the series The Chosen.

Both social media activities sparked some backlash with several accusing her of being ‘right wing’ and one writing of her Hallow app video with the not-so-subtle comment, ‘Make Gwen Stefani Great Again.’
