VIDEO: Carly Rose Watch: Sonenclar Sings 'My Heart Will Go On' on THE X FACTOR

The first time America saw Carly Rose Sonenclar, judge Britney Spears called her a "little diva" and last night the teen lived up to the title with a beautiful rendition of Celine Dion's "My Heart Will Go On" from the blockbuster film Titanic. Check out the performance below!

"Britney, it pains me to say this...but we could be looking at the winner," said L.A.

"Oh, you're so good. And obviously it doesn't make sense. I don't believe that's your voice," said Demi, joking that Celine Dion's hiding in the back.

Judge Simon Cowell remarked, "I don't believe you're a human being because you can't do that at 13. Your control on that song...and that note at the end was absolutely incredible."

Mentor Britney Spears told the singer she had chills.

Sonenclar has appeared on Broadway in Les Miserables and Wonderland, and has also taken the stage in NYMF's The Night of the Hunter (2006) and the national tour of Little House on the Prairie the Musical.
