LOS ANGELES (AP) — For a couple who just announced their divorce, Blake Shelton and Miranda Lambert sure are playful on Twitter. They sent messages back and forth last week touting Ashley Monroe’s album, and Shelton denies reports they were preset tweets. Then Lambert shared a photo of Shelton with a stroller and joked he was pregnant. Shelton responded, “Busted.” However, they both used to have photos of the other on their main pages but both have changed them to neutral ones.
