When Carrie sang Making Love Out of Nothing at All, the teleprompter was visible many times. Im a big Carrie fan and was rewatching her performances, thats why I know. Most likely other contestants use it too. But its seen moving so it must be the lyrics. Its seen everytime the camera moves except when she sings her last note and the camera swings around her, then its turned off. Just thought it was interesting becuase its almost like karaoke.
