In a recent interview with Rolling Stone, the 39-year-old country star opened up about how his relationship with Stefani influenced the album.
"I was spending some time with Gwen all of a sudden, and she became my closest ally, my friend, my person in my life who had my back, and I had hers," Shelton said. "[I] created this bond with somebody that I never would have thought in a million years."
With 153,000 copies of the album sold, If I'm Honest actually sold more physical albums than any other release this week -- country or otherwise -- but it lost the No. 1 spot to Drake's Views because of the rapper's overwhelming number of online streams.
