After years of tabloid gossip, country music's top couple Blake Shelton and Miranda Lambert announced their divorce after four years of marriage. "This is not the future we envisioned," their representatives said in a statement to the AP. "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." Shelton is apparently the one who filed some time ago, reports TMZ, and the divorce is expected to be final today. (More Blake Shelton stories.)
