This is a music video that delivers everything the title promises. Jennifer Lopez and Iggy Azalea are two curvaceous, beautiful women with big butts and this video celebrates those qualities with all the sexy abandon that the material demands. Outfit-stretching bodies fill the screen in vigorously alternating close-ups and longer shots that exert a hypnotic, sensual energy in every frame. The images are a perfect accompaniment to the music, the lyrics and tonality both. We are talking about a song in praise of callipygian women, a high-energy piece of music that captures the anonymous allure of a shapely female backside, and this video gives a face to that anonymity, a strong, confident, beautiful face. From the opening shot of Azalea's oily buttocks filling up her black-and-white swimsuit to the point of overflowing, Sapphic eroticism is given full reign as these bootylicious beauties twerk and twist their fleshy figures all over each other. High point comes when Iggy slaps Lopez twice on her bare ass, right up close and personal! Perfect music video for butt lovers everywhere.
