Blake Shelton is speaking his mind through his music.

Sitting down with ET exclusively, the 39-year-old country star opens up about what fans can expect on his next album -- and when we'll get to hear it.

"I mean, it doesn't take, you know, a rocket scientist. If you have followed my career even a little bit in my life, you know what has happened with me in the last, gosh, eight or nine months," Shelton tells ET's Nancy O'Dell. "It is all on the the record."

Since the release of Shelton's last studio effort, 2014's Bringing Back the Sunshine, much has changed. The singer quickly and quietly filed for divorce from his wife of four years, Miranda Lambert, in July 2015. By the fall, Shelton confirmed that he had begun dating his The Voice co-star, Gwen Stefani, and the pair have been inseparable ever since. On Sunday, the duo made their official red carpet debut as a couple, and Shelton couldn't keep his eyes off his lady as they posed for a portrait by Mark Selinger at the Vanity Fair Oscars party.

Just last month, Stefani confirmed that her latest single, "Make Me Like You," is about her budding romance with Shelton. Now, he seems to be ready to return the favor.

"I can put my life experience, whether it's a divorce or my new girlfriend, whatever those experiences are, whatever things that are happening in my life, I have an outlet for them," Shelton says. "I have music. I can write songs, I can sing about it."

Shelton confesses that he has a new single coming out "really soon," but plays coy about an exact release date.

"New single coming out -- I don't know the exact date," he says. "I do, but I am supposed to say I don't know the exact date."

No slip-ups here! But Shelton couldn't help teasing just a little bit more. "When it comes out, you are going to be like, 'I can't believe he didn't tell me it was going to be that soon!'"

One thing we do know about Shelton's upcoming full-length is that it will feature an appearance from Country Music Hall of Famers, the Oak Ridge Boys.

"In my mind, when I had the Oak Ridge Boys come and sing on my album -- which, I could not be more honored and happy, everything that you can be, it's the Oak Ridge Boys -- so I am thinking, 'Man, this is going to be a perfect secret,'" Shelton says. "'Nobody is ever going to know until this album comes out.' And they came and sang and five minutes later, I looked on Twitter like, 'Oh, they are telling everybody on Twitter right now!'

"What are you going to say, man? It's the Oak Ridge Boys! If they were that excited to be on my record, then I am glad they are out there talking about it," he adds. "It's their world, let them do what they're doing."

Shelton also can't help but gush a little bit about his latest side project, voicing an animated pig in the Angry Birds movie.

"I went in for this meeting to play this pig Earl, and they had a picture of my proposed character on the big screen TV when I walked in," he says. "It was this pig that had on a cowboy hat and he had my tattoo on his arm, he's got like a vest, cowboy boots, and a guitar, he's a country singer. And it was like, 'OK, I don't even know what you're about to say to me, but I'll do it. I'm in!'"

Shelton even penned a song with Jessi Alexander for the big screen project.

"Music was the main thing that I brought to the table," he says. "The song is a very pivotal point in the movie. When you see it, you'll understand. ... It's so much fun! I mean, I never dreamed that I would have that much fun writing a song for a project like that. We did and I couldn't be more excited about it."

But before we hear any new tunes from him, Shelton is busy on the 10th season of The Voice and promoting his new partnership with Smithworks Vodka. Like the singer, who was raised and still resides in Oklahoma, Smithworks was born in America's Heartland and is currently available in Arkansas, Colorado, Missouri, Kansas and Oklahoma.

"It's from where I am from, so the fact that they came to me and I [got the] chance to taste it and they told me that they wanted me to be apart of the making of it," he says, "I was like, 'Gosh, you know. I like vodka.'"

Yes, he sure does.
