Christina Aguilera: 'Keeps Gettin' Better'

Ever since Britney went into meltdown in 2007, fellow pop divas have had to up their games to earn our attention. Prancing around in leather and talking about her "naked Sundays" used to earn Christina Aguilera plenty of red top coverage, but unless she decides to walk through Trafalgar Square in a bikini in her next video, she's always going to look tame in comparison to her fellow Mickey Mouse Club alumnus.

It's nice to report, therefore, that 'Keeps Gettin' Better' is a treat for the ears rather than the eyes. A welcome departure from the hammy jazz sound of her Back To Basics LP, this Linda Perry-penned track is an electropop stomper built around some second-hand Goldfrapp synths and Christina's husky cry of "Some days I'm a super-b**ch!" While it may not generate the same headlines as 'Womanizer', it's more than a match on musical terms.
