Broadway alum Ariana Grande pulled out all the stops both in her outfit's homage to Jessica Rabbit and her classy rendition of her track “Tattooed Heart” at the American Music Awards November 24. With that incredible four-octave vocal range we can see exactly why the star of the Great White Way's 13 was awarded with Favorite New Artist of the Year. Check out the performance that got Lady Gaga to lead a standing ovation below and here's hoping Grande can make time in her busy schedule to come back home to Broadway sometime soon!
