Carrie Underwood is suffering for her art preparing for her leading role in The Sound of Music Live!Thursday night on NBC. She tweeted from rehearsals Tuesday morning, "So, yesterday I hit myself in the head with my own guitar & later fell on my face playing leap frog!"

Carrie and the show's producers made some changes to the script to make sure she doesn't repeat that face plant on camera.

"I no longer leap frog in the show," Carrie later tweeted.

The Sound of Music Live! airs Thursday night at 8 ET on NBC, and fans can get a preview of the music on the show's soundtrack, now on sale. Carrie is featured singing the show's classic songs "Do-Re-Mi," "My Favorite Things" and the title song.
