Beyonce Knowles would like to be known as "Sasha Fierce." Her new double album, "I Am ... Sasha Fierce," is due in stores on November 18.

Beyonce said in a statement, "I have someone else that takes over when it's time for me to work and when I'm on stage, this alter ego that I've created that kind of protects me and who I really am. Sasha Fierce is the fun, more sensual, more aggressive, more outspoken side and more glamorous side that comes out when I'm working and when I'm on the stage."
