TMZ reports the two country superstars filed divorce papers a while ago, and a judge is expected to officially end their 4-year marriage today.
"This is not the future we envisioned," the former couple said in a statement to 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."
