Pop-sensation Britney Spears, who mentored the teenage contestants on the show, thought there was a resemblance between herself and Carly Rose.
“She reminds me a lot of me - when I was younger,” she is quoted on a website run by celebrity-journalist Perez Hilton.
“Carly Rose is kind of shy and then she gets on stage [and] it’s an insane voice.
“Like Simon [Cowell] said about her the other night, she really gets it. She understands the business and that's what you also need on top of being talented. I think that's her best quality."
Carly Rose is the final contestant in the teenage category, and will compete against Tate Stevens, Fifth Harmony, and Emblem3.
The X Factor USA winner will be announced on December 20.
