Irresistible is the second studio album by American recording artist Jessica Simpson, released on May 25, 2001, through Columbia Records. Simpson, who began working on the project in July 2000, contacted already established writers and producers to collaborate on the project, including Cory Rooney, Rodney Jerkins, and Walter Afanasieff. In contrast to her debut album Sweet Kisses (1999), which included more ballads, Irresistible explored hip hop and R&B genres of music. Simpson described the material as "Mariah Carey meets Britney Spears", indicating the soulfulness of the songs as well as their contemporary appeal. Lyrical themes addressed in the album include love and heartbreak, sexuality, and self-respect. At the suggestion of her label executives, Simpson modified her image and sound in Irresistible, deciding to delve more into the teen pop and R&B genres, as she felt that restyling herself to match the image of her contemporaries—Spears and Christina Aguilera—would help rejuvenate her career.
