Donna Summer - Bad Girls

"Bad Girls" is a 1979 single released by American singer Donna Summer, co-written by Summer and the Brooklyn Dreams. The inspiration for her to write the song came after one of her assistants was offended by a police officer who thought she was a street prostitute. A rough version of the song had originally been written a couple of years before its release. Casablanca Records founder Neil Bogart, upon hearing it, wanted Donna to give it to Cher for her upcoming album. Donna refused and put it away for a couple of years.

The song became a number-one hit on the Billboard pop, R&B and dance singles charts simultaneously becoming, alongside "Hot Stuff", her most successful single. The song helped the album of the same name to reach the multi-platinum status in the United States. A 12" single of the song was released as a medley with "Hot Stuff". Although "Hot Stuff" was extended for the 12" single, "Bad Girls" remained in the 4:55 album version. A "Bad Girls" 12" single with a time of 6:55 was produced but never released commercially. A demo version of the song was released on the "Deluxe Edition" of the "Bad Girls" CD.
