Beyonce Knowles' If I Were A Boy has risen two places in this week's singles chart to knock The X Factor Finalists off the top spot.
The former Destiny's Child singer moved up from number three last week to displace the reality show group, whose single is donating half its proceeds to the army's Help For Heroes fundraising charity.
Last week's number two, Live Your Life by T.I. featuring Rihanna, drops two places to number four in its second week on the charts.
And The Killers, whose latest single Human debuted at number four last week, are up one place to number three in their second week.
With no new entries in the top ten this week, the majority of last week's singles simply jostled for position.
Katy Perry's new single Hot N Cold climbed two places from seven to five, displacing The Boy Does Nothing by Alesha Dixon, which dropped one spot to six.
Girls Aloud's Promise is also down one from six to seven, while dance track Infinity by the Guru Josh Project is up one from nine to eight.
Britney Spears' stay in the top ten was extended by another week as she dropped just one place to nine, while Leona Lewis also remains among the top spots with her single Forgive Me staying at ten.
