Carly Rose Sonenclar started singing when she was only 2-years-old - and Simon Cowell factored in her life even back then! "My parents have videotapes of me pretending to be on American Idol and my brother, Russell, made believe he was Simon with the British accent and everything," she says. When Carly was five, she started taking singing lessons and she adds, "I also had a karaoke machine and I would play with it with all of my friends. I sang a lot of Kelly Clarkson songs like 'Behind These Hazel Eyes' and 'Gone.'"

Carly, who is one of Britney Spears' Teens, first started singing professionally at age seven in the Off-Broadway show, The Night of the Hunter. Later, she appeared in the Broadway production of Les Miserables and in 2009, played Carrie in the national tour of Little House on the Prairie: The Musical. Carly's credits also include the Broadway show Wonderland and the PBS TV series The Electric Company.

Recently, the young singer has been pursuing her solo music career, performing at Birdland Jazz Club in New York and writing her own songs. She says, "I want to bring the soul back to pop. My record would be a mix of those two genres because I think that is something that is not really out there right now. I could fill that gap and appeal to a wide range of ages. I think I have the X factor because I have a uniquely mature sound and style for my age."
