Britney Spears, Leona Lewis, Beyonce And Christina Aguilera will go head-to-head with each other in the UK charts next week.

Each singer is scheduled to release their new single on November 3rd, which has now been dubbed 'Super Monday'.

Spears is expected to win the battle to number one with 'Womanizer' - the first track to be taken from the her new album 'Circus'.

But former X Factor winner Lewis, who releases her new studio album later this year, is expected to push the singer close in the race.

Aguilera and Knowles' new releases, 'Keeps Gettin' Better' and 'If I Were A Boy', are also lead tracks from their new albums.

HMV spokesman Gennaro Castaldo told the Sun newspaper: “We haven’t had a heavyweight chart battle like this for a while. It’s wide open but you have to fancy Britney, perhaps just ahead of Leona.”

As previously reported, Beyonce said last week that she would like to be known as Sasha Fierce for her new album.

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