Blake Shelton and Miranda Lambert Divorce: New Details Revealed as Cheating Rumors Swirl

Did Miranda Lambert cheat on Blake Shelton?

More details are emerging about country stars Blake Shelton and Miranda Lambert's surprising split.

According to court documents, Blake filed for divorce on July 6, in Pottawatomie, Oklahoma. He used their initials when filing, referring to themselves as "B.T.S." and "M.L.S." -- Blake's full name is Blake Tollison Shelton, while Miranda's full name is Miranda Leigh Shelton. The divorce has already been finalized by an Oklahoma judge, though the divorce documents are sealed.

Miranda will get their Nashville property and Blake will get their ranch in Tishomingo, Oklahoma, Us Weekly reports. The former couple had everything "spelled out" in a prenuptial agreement, the source says, making it easy for both to agree to the terms.

Though the split certainly caught the superstar couple's fans by surprise on Monday, the two weren't spotted together all throughout the American Country Music Awards ceremony when ET went backstage in April. In fact, Miranda admitted she wasn't really sure of her then-husband's whereabouts.

"I haven't seen him all day because he's been rehearsing, but the last state I saw him in, he was pretty good, but you know, that was a couple hours ago so I'm not really sure what's going to happen," she told ET. She also didn't thank him during any of her acceptance speeches that night after winning three different awards.

Meanwhile, cheating rumors on both sides have been reported. TMZ alleges that 39-year-old Blake suspected 31-year-old Miranda of hooking up with country singer Chris Young, though it was another man he believed she was unfaithful with -- who's not a country singer -- that was the catalyst for divorce. However, Chris -- who previously toured with Miranda, serving as her opening act on 2012's On Fire Tour -- shot down the report on Facebook on Tuesday.

"I don't normally address gossip but in this case I will," Young wrote. "My name has been mentioned as a contributing factor in Blake and Miranda's divorce. That is totally FALSE. They are both my friends and I would not betray that friendship. Just wanted to clear that up."

Though, it's also worth noting that Blake has himself been accused multiple times of cheating on Miranda while they were still married.

But according to E! News, it was both of the stars' busy schedules that actually put the strain on the marriage. "They both worked a lot and had to spend a lot of time apart," a source says. "The less time they spent together, the more they grew apart."

Miranda is reportedly "sad and trying to process everything" post-split, People says.

"She's doing the best she can and taking it day by day," a source tells the magazine about her current state of mind.

Blake and Miranda tied the knot in May 2011 after five years of dating. The nuptials marked the first marriage for Miranda, and the second for Blake.

"This is not the future we envisioned," the pair said in a joint statement on Monday about their split. "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."

In hindsight, there were definitely signs of the pair's split before the big announcement. Just days before the news broke, Miranda broke down during her Cheyenne Frontier Days concert in Wyoming, and also did not appear to be wearing her wedding ring. Watch below:
