She sang parts of "My Favorite Things," "Edelweiss," "The Sound of Music" and "Climb Ev'ry Mountain," earning thunderous applause from the audience and an accolade from the most iconic version of the musical's singing nun.

"Thank you Lady Gaga for that wonderful performance," said 79-year-old Julie Andrews, taking the stage after the performance.
