Last week, a star was born on "The X Factor." When 13-year-old Carly Rose Sonenclar took the stage -- wearing sandals and jean shorts -- and announced that she would be singing "Feelin' Good" by Nina Simone, the judges were more than a little bit skeptical. Simon Cowell raised his eyebrows and said "WHOA" when she announced her choice of song, and LA Reid asked skeptically, "Did you rehearse?"

But the Westchester, New York native blew the judges' expectations out of the water with her dynamite performance, earning four enthusiastic "YES"'s and a standing ovation from the crowd. Britney Spears declared, "All of us are completely in love with you!" while Demi gushed, "I want to buy your music right now." Watch the video above to view her incredible performance and see the judges' reactions.

She may not have won the competition (yet), but she's already won over the Internet. The clip of Carly singing "Feelin' Good" has racked in over 1.5 million views on YouTube.

Other stars from last week's "X Factor" include 20-year-old Jillian Jensen, who sang a heartfelt rendition of Jessie J's "Who You Are" that earned her a big hug from Demi Lovato on Wednesday. On Thursday night, Jason Brock also stole the show by singing a unique version of "New York State of Mind," prompting Demi to say, "It makes me wanna fall in love with you."
