In a new interview with Katie Cook of CMT's Hot 20 Countdown
, the "Came Here to Forget" singer gets candid on his relationship
with the No Doubt frontwoman, even crediting her for saving his life.
"It's not something that anybody could have seen coming, besides God, I guess," the 39-year-old country crooner says of his first spark with Stefani. "It doesn't look like it would make sense, you know? But all I can tell you is, it does, it just makes the most perfect sense for us and where we're at in our lives."
"I tell people all the time, 'Gwen saved my life last year,'" he continues. "She did, and I think she would probably tell you something similar about me."
"I think that when you go through what I went through, or what I'm still going through, you think you're hopeless. You don't know what's going to happen. You panic," Stefani told Refinery29
in March. "It was a really super-unexpected gift to find a friend, somebody who happened to be going through the exact same thing as me, literally mirroring my experience. I don't think it's an accident that that happened. It saved me."
Shelton says that when the two first started working together during season seven of The Voice, they really didn't know each other that well, only exchanging a "high-five" or a "Good to see ya!" every once in a while.
"Even coming into [her] second season [working on] The Voice, I didn't even really know her that well," he adds. "All of a sudden this thing just happened because of some things we were going through and it saved my life, period."
Shelton and Stefani, 46, officially became a pair
in November, a few short months after the two both announced they were getting divorces -- Stefani called it quits with Bush frontman Gavin Rossdale
in August, while Shelton split from fellow country artist, Miranda Lambert
, in July.
On his 10th studio album, If I'm Honest
, Shelton sings about the ups and downs of falling in love, seemingly referencing his relationships with Stefani and Lambert in some of the tracks. While speaking with CMT, the Oklahoma native also got candid about what it was like recording songs for the album, specifically "Go Ahead and Break My Heart
," which features his girlfriend's vocals.
"It was odd because we wrote the song last fall sometime," he says of the writing process with Stefani. "I started the song just because I was trying to impress her
. I sent it to her on voice memo on her phone, and I like just texted it to her, and I said, 'Here's something I was writing, I was thinking about everything.'"
"It was only half done and she wrote the next verse of the song and sent it back to me a couple of days later," he continues.
"What happened was, the story is, that he had written the song and sent it to me on my phone. I was scared to listen to it," she admitted. "I was like, 'What if I don't like it?' And I listened to it and I'm like, 'Oh my God, I love this.' He said, 'Write the rest of it.' It was a time when I was really insecure about writing."
"I never thought I would have new music," she added. "I never thought any of this stuff would happen. It's the craziest year of my life."
In addition to coupling up and collaborating with Shelton, she also released her own album, This Is What the Truth Feels Like
. She's now gearing up for the album's subsequent summer tour
, which kicks off on July 12 in Mansfield, Massachusetts.
