Is it more shocking that Britney's latest single is about having a threesome, or that it's taken Britney a full decade to tackle such fruity/fruitful subject matter? Either way, '3' makes for a fitting addition to her upcoming 'Best Of' comp - pure pop with a soupçon of controversy, it's pretty much elemental Spears.

The chorus is a naggingly catchy playground chant, Max Martin's production is as sweet and shiny as a glacé cherry, and the surprisingly inventive lyrics even manage to sneak in a WTF?! reference to '60s folk trio Peter, Paul and Mary. Oh, and right at the end Britters admits that ménage a trois might be insufficient to sate her appetite, proposing a "four on the floor" jobby instead. Well, at least finding willing participants shouldn't be a problem - don't all of the boys and all of the girls want to...?
