Just like the "Seinfeld" episode where George wanted everyone to call him "T-Bone," Beyonce Knowles would like to be known by a bold new name.

The R&B singer has christened herself "Sasha Fierce" for her new double album, "I Am ... Sasha Fierce," due in U.S. stores on November 18, and has released a lengthy justification for the comical moniker.

"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," the former Destiny's Child frontwoman said in a statement.

"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."

Additionally, she has set up a cryptic MySpace page (http://www.myspace.com/sashafierce) that gives a "lucky person" the opportunity to receive a personal message and a gift bag valued at $500.

As George found out, nicknames usually do not work when they are self-bestowed. His colleagues thought he should be called Koko the monkey. In real life, rapper Eminem had better luck with his alter ego "Slim Shady," which he said came to him while he was on the toilet.

Beyonce released her previous solo album, "B'Day," to coincide with her 25th birthday in September 2006. It debuted at No. 1 on the U.S. pop chart and yielded the No. 1 single "Irreplaceable."

"I Am ... Sasha Fierce" will be distributed by Columbia Records.

Beyonce Knowles is quite the slave name.

I still think Destiny's Child sounds like the name of a power metal band.
