US R&B star Beyonce has said she would like to be known as Sasha Fierce for her new album, 'I Am...Sasha Fierce'.

The album, which is due to be released on November 18th, is the singer's follow-up to 2006's 'B'Day'.

The former Destiny's Child star said Sasha Fierce is her more “fun, more sensual, more aggressive, more outspoken side and more glamorous side” that comes out when she performs.

She added: "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."

Beyonce has also launched a new Myspace page for the pseudonym, which is currently offering a “lucky person” the opportunity to win a personal message and $500 gift bag.

'I Am...Sasha Fierce' features Beyonce's much anticipated collaboration with Justin Timberlake.
