Hold on to your witch hats, because Ariana Grande [1]'s performance on NBC's Wicked special [2] is about to blow you away. While Kristin Chenoweth [3] and Idina Menzel gave fabulous performances of their hit songs, Grande really brought the house down (pun intended) with her rendition of "The Wizard and I. [4]" Dressed from head to toe in black and green, the singer showed off her incredible voice as she hit all the right notes. See her gorgeous performance ahead!
