Well, that was quick. Divorce papers were finalized on the same day country stars Blake Shelton and Miranda Lambert announced their split, Us Weekly reported Monday. Shelton, who is a judge on NBC’s “The Voice,” filed divorce documents in Oklahoma two week ago. A judge signed off on the papers Monday, Us Weekly added.

Infidelity wasn’t given as a reason for the divorce when the singers issued a joint statement to the Associated Press. “This is not the future we envisioned," the stars said. "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."

But that hasn’t stopped the rumor mill from churning. Fans on Twitter suspected Shelton cheated on the “Little Red Wagon” singer. And speculation doesn’t come from nowhere. The “Sangria” singer is a known flirt. He admitted he started to fall in love with Lambert when he was still married to his first wife, Kaynette Gern.

"I’ve never had that kind of experience with anybody," he said about the first time he and Lambert met, which was at CMT's 100 Greatest Duets Concert in 2005, according to Us Weekly. "I was a married guy, you know? Standing up there and singing with somebody and going, ‘Man, this shouldn’t be happening.’ Looking back on that, I was falling in love with her, right there on stage."

There hasn’t been any proof that Shelton cheated. “Blake is just that incredibly loyal and dedicated husband," a source told People magazine after the split. "I can guarantee you he has been faithful to that woman." The insider added: "He hasn't cheated ever.”

Shelton, 39, and Lambert, 31, married in 2011 after six years of dating. They do not have any children together. They reportedly signed a prenuptial agreement.
