The news of Blake Shelton and Miranda Lambert's split earlier today came as a shock to many, especially considering how hard they've fought to debunk the rumors of trouble in paradise over the course of their four-year marriage.
E! News confirmed earlier that Shelton had filed divorce papers, and shortly thereafter the two released the following joint statement:
"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."
And now, a source explains just what really went down in the famous couple's highly publicized relationship, and what lead to their decision to part ways.
"Their busy schedules were a big issue for them. They both worked a lot and had to spend a lot of time apart. The less time they spent together, the more they grew apart," our source shared.
