Britney Spears and Iggy Azalea enjoy a blast from the past in the music video for their new single Pretty Girls. Set in the 1980s with a not-so-subtle wink to Earth Girls Are Easy, the clip sees Britney doing her best impression of Geena Davis in the 1988 cut film - complete with Valley Girl accent. She embarks on a road trip with her new best friend Iggy, who just so happens to be an alien, while they both leave little to the imagination in a series of sexy outfits.
