Italian. I especially have to tell you though, Renata Fusco and Luca Velletri did an awesome job! They are also the Italian singing voices of Lady and Tramp in the Italian dub of Lady and the Tramp 2: Scamp’s Adventure. Awesome that they did a couple together twice in a Disney direct-to-video sequel, and a movie based on a Broadway musical
Has nothing to do but the french singers of Christine (Cecilia Cara) and Raoul (Damien Sargue) both played a musical of Romeo and Juliet, I recommend you a lot to watch it, you'll love their voices it is called Romeo et Juliette de la haine à l'amour (2001)
