STAGE TUBE: Carly Rose Sonenclar Sings 'Brokenhearted' on THE X FACTOR

On last week's episode of FOX's THE X FACTOR, Broadway's Carly Rose Sonenclar performed an amazing rendition of Karmin's 'Brokenhearted' at Britney Spears' home. Check out her performance below!

Carly, who is twelve years old, played 'Chloe' in Broadway's 2011 "WONDERLAND- A New Alice. A New Musical." Her other credits include Les Mis and The Electric Company. She recently made her Birdland debut at the American Cancer Society Benefit, We're Gonna Have To Ask You To Leave this January.

Since its debut in 2004, THE X FACTOR has remained the U.K.'s #1 program for the last seven years, peaking with an audience of 21 million for its 2010 finale. The format swiftly broke similar records around the world, where local versions have consistently rated #1. The series has received numerous honors worldwide, and more than 100 million records have been sold by artists launched through the series, including over 90 #1 singles and albums and 150 Top Ten records.

In a departure from other singing competition series, the first time contestants audition for THE X FACTOR judges, Simon Cowell, Antonio "L.A." Reid, Britney Spears and Demi Lovato, they will do so in front of an audience of thousands - raising the stakes and increasing the pressure to impress not only the judges, but also a potential legion of fans. This will be the ultimate test to prove they have the vocal ability, charisma and stage presence that it takes to win an unprecedented $5 million recording contract with Syco/Sony Music.
