It was only very recently that Iggy Azalea and Britney Spears’ collaboration ‘Pretty Girls’ was released for the world to hear, and needless to say it was everything that we would expect of a Britney/Iggy collaboration. Dance routine? Check. Rap section? Check. Catchy hook? Check. After only hearing the song once I was actually catching myself wandering around the house singing the chorus! Britney and Iggy’s song is certainly a contender for the most catchy song of the American summer, a spot that was arguably held by Iggy’s smash-hit ‘Fancy’ last year. However, is this song really the piece of fun, pop goodness that it seems, or is there something a little less sweet hidden beneath the sugar-coating?
