Blake Shelton Says He and Gwen Stefani 'Could Not Be Any More Different'

The 'Came Here to Forget' singer continues to gush over his 'fun' relationship with the No Doubt frontwoman.

Blake Shelton is just being honest -- about love, that is!

The "Came Here to Forget" singer was a guest on the Today show on Thursday, where he joked that since everybody else is "cashing in" on his life and his highly publicized relationship with Gwen Stefani, he "might as well, too."

"It's a little weird, but I get it," he explained about all the attention he's received from fans and the media in regard to his and Stefani's chemistry. "We could not be, on paper, any more different. I mean, I'm a country singer and she's a ska, rock, pop, whatever it is, and it's just an odd idea. But man, it's a lot of fun. I've gotta be honest about that."

Honest, indeed! Shelton puts his heart on the line in his latest album, If I'm Honest, which will officially be released on Friday.

"I had a bunch of different ideas [for the album's title]," he said. "I gotta hand it to a friend of mine that works at Warner Bros. named Shane Tarleton. I was going, 'I want it to be representative of the last year of my life,' and I was even talking about stupid stuff like, 'How many moons are there in a year?'"

"He was like, 'Man, why don't you just say you're being honest about what happened the last year?'" he continued. "So that's how we came up with that album title."

"It's been fun," Shelton, 39, added. "I mean, I feel like I'm doing what I'm supposed to be doing as a country artist, which is sing about my experiences, so that's basically what the entire album is."

The country crooner seemingly references his relationship with Stefani in some of the tracks, as well as his ex-wife, Miranda Lambert, whom he split from last July. Shelton and Stefani, 46, became a pair in November, a few short months after the "Misery" singer divorced from her ex-husband, Gavin Rossdale.

Shelton even had Stefani help him write one of the tracks on his 10th studio album, a powerful country duet titled "Go Ahead and Break My Heart." The adorable duo performed it for the first time on The Voice last week, and again on Wednesday on the Honda Stage at the iHeart Radio Music Theatre in Los Angeles. Shelton says he couldn't be happier with the reaction it's gotten.

"It's been crazy," he explained, noting that the two will also perform it on Sunday at the 24th annual Billboard Music Awards. "I actually wrote that song, started it just to try to impress her, to be honest with you. And I sent it to her just half done, and she wrote the next verse and sent it back to me. And so it was like, 'Well, we've got a song together. That's kind of cool.'"

Shelton hasn't been shy about gushing over his rocker girlfriend. In an interview with CMT's Hot 20 Countdown, the Oklahoma native credited the No Doubt frontwoman for saving his life.

"It's not something that anybody could have seen coming, besides God, I guess," he revealed. "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 continued. "She did, and I think she would probably tell you something similar about me."
