(CMT Offstage keeps a 24/7 watch on everything that's happening with country music artists behind the scenes and out of the spotlight.)

Carrie Underwood put it so simply. "There are no words," she tweeted after the school shooting in Newtown, Conn., on Friday (12/14). Twenty children and six faculty members at Sandy Hook Elementary school were shot and killed by gunman Adam Lanza before he killed himself. Country artists -- along with the rest of us -- shared their heartfelt prayers and sentiments and questions with the world via Twitter and Facebook. Underwood's complete tweet was, "All my thoughts, prayers and deepest sympathies go out to the families in CT dealing with this tragedy. There are no words."

Taylor Swift wrote, too, saying, "I'm heartsick about the senseless tragedy in CT and praying for the families of the children and teachers who lost their lives. Unthinkable."

Tim McGraw took three tweets to string his thoughts together. "The news of this morning's shooting was simply devastating. As parents, Faith and I cannot even imagine the horror that all of these families face. Our deepest thoughts and prayers are with all that have been affected by this tragedy," he wrote.

And Luke Bryan asked the world to pray for Connecticut, and wrote, "My family is sending the deepest prayers out to those victims in Connecticut today. Heavy hearts and tears."

Keith Urban, too, was sending his prayers out. "My heart goes out to all those affected by the tragedy in Connecticut. Thoughts and prayers with everyone," he wrote.

Blake Shelton's response was a patriotic one. "Stand strong and stand united everyone. ... We are Americans and we are better than this. What a sad sad disgusting day this is," he said. And his wife Miranda Lambert wrote, "I'm praying for those babies and all the victims of the Connecticut shooting. May God bring peace to the families."

Brad Paisley sounded equally angry and emotional in his response. "I spent 15 minutes yelling at the top of my lungs about what happened in Connecticut," he wrote. "I'm as mad as I am sad. Enough. Enough!!!!!!"
