Gwen Stefani has a not-so-typical strategy for keeping her marriage strong with country star Blake Shelton, whom she married in 2021, the New York Postreported. Appearing on The Drew Barrymore Show, the 55-year-old singer shared that the couple relies on a “third party” to help keep their relationship thriving. But it’s not what you might expect—Stefani clarified that she was referring to God, as she looked up and pointed to the sky. The “Hollaback Girl” singer claimed that the best advice she ever received was “make sure you have a third party.” Stefani has long been a devout Catholic and has partnered with the Hallow app in an effort to encourage more people to pray. Stefani and Shelton first met in 2014 when she was a coach on Season 7 of The Voice. At the time, both of them were married—Stefani to Gavin Rossdale and Shelton to Miranda Lambert. However, by July 2015, the couple finalized their divorces. After the “God’s Country” singer won her over with a song, Shelton and Stefani officially began dating in 2015 and got married in July 2021 in an intimate ceremony on Shelton’s property in his home state of Oklahoma.
