Beyonce has announced that from this point forward she would like to be known as  ‘Sasha Fierce’..at least when she’s on stage. B says that when she steps on stage Sacha takes over and that’s when things start getting nasty.

“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. 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.”

In real life, Beyonce Knowles is quiet, mousy librarian who lives with 18 cats and watches HSN 10 hours a day.

Sacha’s new album, cleverly titled “I Am…Sasha Fierce” will hit the shelves on November 18, but in the meantime you can check out Sasha’s new MySpace page. It’s …wait for it….FIERCE!
