Overview: In the Zone was promoted with four singles. "Me Against the Music", featuring Madonna, reached the top ten in nearly every country except the United States, where it only peaked at number 35 on the Billboard Hot 100. "Toxic" peaked atop the charts in eight countries and at number nine on the Billboard Hot 100, becoming Spears' first US top-ten hit since "Oops!... I Did It Again" (2000), and won Spears her first Grammy Award. "Everytime" peaked at number 15 on the US Billboard Hot 100 and within the top ten nearly everywhere else. "Outrageous" was plagued by a lack of promotion due to Spears injuring her knee while filming its accompanying music video, and only peaked at number 79 on the US Billboard Hot 100. To further promote the album, Spears embarked on the Onyx Hotel Tour (2004).
