Carly has made it to the top six finalists in the competition. Britney Spears is currently her on-screen mentor.
X Factor judge LA Reid praised the pint-sized powerhouse as one of her "best" so far. "What I loved about that performance is that you actually showed some restraint," he said.
Demi Lovato claimed Carly actually "sang it better than Justin did".
Even the usually sour Simon Cowell was charmed by Carly's talent. "This is why I love working in this country. We find people like you," he said.
LA Reid was one of the producers responsible for launching Justin Bieber's career. Will he do the same for Carly Rose Sonenclar?
