Just one day before dropping a divorce bombshell, Blake Shelton's wedding band was on full display.

The country star was photographed at a NASCAR race in Loudon, New Hampshire, on Sunday, exchanging a few words with Adam Sandler. Less than 24 hours later, he and Miranda Lambert announced that they would "move forward separately" with a divorce.

According to reports, the couple's official split has been in the works for quite some time. TMZ states that Shelton filed divorce documents "a while ago" and that a judge only finalized the process on Monday.

Meanwhile, Shelton has yet to change his official Twitter cover photo, which has long been a snap of Lambert's Marie Claire cover. In the mag's December 2014 feature, Lambert called her then-hubby her "perfect match."

"I'm not sunshine and roses. Blake's the happiest person on the planet. He pulls me out of my darkness," she said. "Literally everything is the best about being married."

Over the weekend, Lambert became visibly emotional performing her hit, "Over You," which she co-wrote with Shelton. The song earned the couple an Academy of Country Music award back in 2013.

And she wiped away tears while singing "The House that Built Me."

As the couple moves forward, Lambert will continue her Platinum Tour with the just-announced Roadside Bars & Pink Guitars Unplugged show in Nashville, Tennessee, on July 28. Shelton will play Country Jam USA in Eau Claire, Wisconsin, on Friday, July 24.

At the moment, neither Lambert nor Shelton has spoken publicly about the split -- save for a carefully-worded joint statement.

"This is not the future we envisioned," reps for the pair told the Associated Press. "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."
