Carly Rose Sonenclar proves that big voices can come in small packages.

The 13-year-old singer killed it on Divas Night on "The X Factor" on Wednesday, upping her game with her version of Celine Dion's "My Heart Will Go On."

Celine is definitely a tough one to compete with, but Carly held her own ... and the judges were all very impressed.

"We could be looking at the winner," said L.A. Reid -- while Demi Lovato added "I feel like Celine Dion is here and she's hiding."

Simon Cowell was shocked as well, telling her "I don't believe you're a human being. You can't do that at 13. Your control on that song and that note on the end was absolutely incredible."

And mentor Britney Spears was beyond proud, saying "I had chills all over my body, you're spectacular."

toofab reached out Celine Dion and her husband/manager Rene Angelil, and the couple told toofab exclusively that they were "blown away" by Carly Rose's performance. Rene added that the teen's rendition "reminded me of a 12-year Celine ... when I first discovered her."

How do you think she did? And are you guys still watching the show? Sound off below.
