"The Shoop Shoop Song (It's in His Kiss)" is a song written and composed by Rudy Clark. It was first released as a single in 1963 by Merry Clayton that did not chart. The song was made a hit a year later when recorded by Betty Everett, who hit No. 1 on the Cashbox magazine R&B charts with it in 1964. Recorded by dozens of artists and groups around the world in the decades since, the song became an international hit once again when remade by Cher in 1990.

The song was rejected on behalf of the premier girl group of the early 1960s, the New York-based Shirelles, and was first recorded in Los Angeles by Merry Clayton as her first credited single. Clayton had previously provided an uncredited female vocal to the hit "You're the Reason I'm Living" recorded by Bobby Darin as his debut on Capitol Records, and Darin had subsequently arranged for Clayton herself to be signed to Capitol. The composer of "It's in His Kiss", Rudy Clark, was a staff writer for TM Music which Darin headed. Clayton's recording of the song was produced by Jack Nitzsche, and featured Hal Blaine on drums and the Blossoms as chorus. It was released as a single on June 10, 1963, without success.

Clayton recorded the song again for the soundtrack of the 1987 comedy film "Maid to Order" in which she, as the character Audrey James, performs with fictional band the Loaded Blanks, played by the rock band Great White, in the film's climactic scene.

Calvin Carter, the chief A&R man for the Chicago-based Vee-Jay Records, found "It's in His Kiss" while visiting New York City in search of material for the Vee-Jay roster which included Betty Everett. After Everett had a hit with another song Calvin Carter brought back from New York City, "You're No Good", Calvin Carter suggested Everett cut "It's in His Kiss" as the follow-up single. Everett – who found the song puerile – reluctantly agreed. The accompanying vocals on Everett's recording were provided by Vee-Jay session regulars the Opals, a trio of teenage girls (Rose Addison, Myra Tillison, and Rose "Tootsie" Jackson) from East Chicago, Indiana.
