Country music star and "The Voice" coach Blake Shelton has broken his silence over his recent divorce from fellow country singer Miranda Lambert.

While "my life is all over the papers," Shelton lamented Wednesday on the nationally syndicated radio program "The Bobby Bones Show," he and Lambert nonetheless had kept the divorce filing secret until announcing their breakup virtually the moment the divorce was finalized.

"In Oklahoma," he explained, "it happens so fast. Miranda and I didn't have any kids, and we had, y'know, [a] prenuptial agreement, whatever we had. So it was, like, once we filed for divorce it was over in -- I think it was like a 10-day, 9- or 10-day waiting period until it's over. . . . Even if we [had known] of rumblings and rumors . . . coming out, they would just be that. Because by the time anybody knew anything, it was over. "

He added: "Our whole thing was, man, y'know, we're just going to be cool about this. It is what it is. Y'know, we're buddies."

Shelton, 39, and Lambert, 31, released a joint statement about the divorce on July 20.

It said, "This is not the future we envisioned. And it is with heavy hearts that we move forward separately. We are real people, with real lives, with real families, friends and colleagues. Therefore, we kindly ask for privacy and compassion concerning this very personal matter."
