R&B singer Beyonce Knowles has a cool distinctive name, but she’s not happy with it. She’s just christened herself “Sasha Fierce” for her new double album, “I Am … Sasha Fierce,” due to drop in stores on November 18.

Why the change? The former Destiny’s Child singer says: “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.”
