Italian singer Andrea Bocelli is known for being one of the most talented vocalists of all-time. Fans were surprised recently when Bocelli made the decision to team up with pop singer Ariana Grande to sing a duet. As soon as fans heard the results of their collaboration, however, they no longer had any doubt as to why he decided to sing with her!

Grande joined Bocelli to sing “E Più Ti Penso” for his new album. As soon as the two start to sing, they left their fans speechless with the magical sound that they make together. Their voices sync up perfectly, and the harmony of their music takes on a breathtakingly haunting quality.

Though Grande is 35 years younger than Bocelli, she is more than able to hold her own as she sings with him. Bocelli is a legendary opera powerhouse, but Grande is able to keep up with him by showcasing her own vocal range. Of course, Bocelli is perfection personified as always, and his voice is sure to send chills down your spine.

You may recognize the song they are singing from the movie Once Upon A Time In America. Bocelli and Grande sing the lyrics with even more power than the original performer, and the results are nothing short of astounding.

Social media users can’t get enough of this collaboration.

“They both sound like beautiful instruments. Andrea is like a cello. Ariana is like a violin. This was beautiful. I wish she tapped into this side of herself more,” one user wrote, another adding, “SWOONING!!! Andrea Bocelli is a legend amongst male vocalists. I would love to see him perform live. Ariana’s voice is incredibly rich and warm as well. Love this.”
