Carly Rose Sonenclar performed “My Heart Will Go On” leaving the judges of X Factor stunned. They just couldn’t believe what they saw and heard.

“You’re so good! It just doesn’t make sense. Like I don’t believe that that’s your voice,” Demi Lovato told her. “I feel like Celine Dion is here and she’s hiding.”

Quipped Simon Cowell, “I don’t believe you’re a human being. Because you can’t do that at 13.”

And L.A. Reid told Sonenclar’s mentor Britney Spears, “Britney, it pains me to say this. I don’t want to say this [but] we could be looking at the winner.”

Spears herself said she had “chills all over my body,” and called Sonenclar “spectacular.”
