Guess Who This Lil' Singing Star Turned Into!

Before this little singer's pipes blew away America (and Simon Cowell), she was just getting all dolled up in her white dress, gearing up for her big solo and growing up in Chicago, Illinois with her sister and brother.

From the American Idol stage to the big screen, this singing machine can also act, and she played the smart and comical assistant to Carrie Bradshaw (played by Sarah Jessica Parker) in "Sex And The City: The Movie."

Need one more hint? She was a "Dreamette" alongside Beyonce and Anika Noni Rose.
