Dirrty

"Dirrty" is a song by American singer Christina Aguilera featuring American rapper Redman, released as the lead single from her fourth studio album Stripped. Despite Aguilera's first three years of commercial success, she was displeased with the lack of control over her image. In response, she desired to create a song that would represent her authentic persona. She approached hip hop producer Rockwilder and suggested using Redman's 2001 song "Let's Get Dirty (I Can't Get in da Club)" as a guide. The final result, "Dirrty", is an R&B and hip hop song that also features rapping verses from Redman and describes sexual activities.

RCA Records sent "Dirrty" to American radio stations on September 3, 2002, as the lead single from Stripped. RCA and Bertelsmann Music Group later released the song as a CD single. The song peaked at number 48 on the US Billboard Hot 100. Outside of the United States, "Dirrty" saw significant success in the British Isles, topping the charts in Ireland and the United Kingdom. Elsewhere, the song peaked within the top ten in many countries including Australia, Denmark, Germany, the Netherlands, Spain, Sweden and Switzerland.
