LOS ANGELES – Country music superstars Blake Shelton and Miranda Lambert said on Monday they have divorced after four years of marriage. Shelton, a judge on the popular TV show “The Voice,” and Lambert made their announcement following years of gossip in celebrity magazines that their marriage was in trouble. “This is not the future we envisioned,” the couple said in a statement issued through their representatives. “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.” The two did not say when the divorce proceedings took place. Shelton, 39, has seen his career soar during his four years on the NBC singing competition “The Voice,” and he hosted the Academy of Country Music Awards for four years. Lambert, 31, is one of country music's most successful female artists, winning Academy of Country Music awards for female vocalist of the year and album of the year for her 2014 album “Platinum.” – AP
