Are you ready to get the chills? Good, because Jessie J is here to prove why she’s so much more than just a pop singer.

The English performer shared a video on Instagram of her covering the ballad “On My Own” from Les Misérables, and it will honestly make your jaw drop. Her powerful voice might shock some who only know Jessie J from her songs like “Bang Bang” and “Price Tag,” but she’s here to remind everyone that her background is actually much different than what you’d expect.
