The music video for "Dirrty" was directed by David LaChapelle. The video opens with Aguilera gearing up and riding a motorcycle into a nightclub. Wearing a bikini and buttocks-bearing chaps, she is lowered from a cage into a boxing ring and dances, accompanied by several back-up dancers. A masked woman is lowered into the ring, and the two engage in foxy boxing. The scene is inter-cut with sequences of Aguilera dancing in a crop top, which she later removes to reveal a bra, and a micro-skirt. Redman then proceeds down a hallway, passing people such as mud wrestlers, a contortionist, and furies. The video proceeds to a scene of Aguilera and back-up dancers splashing and dancing while being sprayed with water in a room containing several urinals. It features several sexual fetishes, from mud wrestling to muscle worshiping.
