Emmanuelle Grey "Emmy" Rossum was born in New York City to a Jewish American family; her father is a banker and her mother is a corporate photographer. Her parents divorced when she was three years old and Rossum has not remained close to her father. At seven years old, Emmy made $5 a night at the Metropolitan Opera singing with the children's choir.
According to her, "There were horses onstage that were getting $150." At age seven, she joined the Metropolitan Opera Children's Chorus and was asked to sing Happy Birthday for her audition. Rossum was enrolled at the prestigious all-girl Spence School in Manhattan until administrators upset with her frequent absences delivered an ultimatum - forego all career opportunities in order to concentrate on schoolwork, or withdraw. She opted for the latter, and graduated from high school after completing "virtual classes" sponsored online by the University of Nebraska-Lincoln.
She left the school to pursue an acting career. Just recently she's pursued a singing career after the success of Phantom of the Opera.
