The country music superstar is gonna shine in the new "Sound of Music" broadcast.
In a production to be aired late next year, the 5 time Grammy winner will star as the rebellious would be nun who married Austrian Naval commander Georg Von Trapp and fled the Nazi's with him and his children.
She will sing "My favorite things" and other tunes.
NBC did not say where the musical will be staged but did say they couldn't be happier to have the gifted Carrie Underwood take up the mantle of the great Maria Von Trapp.
Robert Greenblatt,Chairman of NBC Entertainment said in a statement."She was an iconic woman who will now be played by an iconic artist."
