2003–2005: In the Zone and first two marriagesIn August 2003, Britney Spears performed "Like a Virgin" at the MTV Video Music Awards with Christina Aguilera. They were later joined by Madonna, with whom they both shared a highly publicized kiss. The incident is now considered one of the most memorable moments in the history of the MTV Video Music Awards. That year, Spears released her fourth studio album, "In the Zone," which marked her growth as a songwriter as she took more creative control over her music. The album debuted at the top of the charts in several countries, including the United States, making Spears the first female artist in the SoundScan era to have her first four studio albums debut at number one. The album spawned four successful singles, including a collaboration with Madonna, "Me Against the Music," and "Toxic," which won Spears her first Grammy for Best Dance Recording.In January 2004, Spears made headlines with her short-lived marriage to childhood friend Jason Allen Alexander. The two were married in Las Vegas but annulled the marriage just 55 hours later, stating that Spears "lacked understanding of her actions." In March 2004, she embarked on The Onyx Hotel Tour in support of "In the Zone." However, in June 2004, Spears fell and injured her left knee during the music video shoot for "Outrageous," resulting in surgery and the cancellation of her tour. That same year, Spears became involved in the Kabbalah Centre through her friendship with Madonna.In July 2004, Spears got engaged to dancer Kevin Federline, whom she had met just three months earlier. Federline had recently ended his relationship with actress Shar Jackson, who was pregnant with their second child. Spears and Federline's relationship was the subject of a reality show, "Britney and Kevin: Chaotic," which premiered in May 2005. Spears later referred to the show as "probably the worst thing I've done in my career." The couple got married in September 2004, but due to a delay in finalizing their prenuptial agreement, they were not legally married until October.Shortly after, Spears released her first perfume, "Curious," with Elizabeth Arden. The fragrance broke the company's first-week gross for a perfume. Spears then took a career break to start a family. In November 2004, she released her first greatest hits compilation album, "Greatest Hits: My Prerogative." In August 2005, she released "Someday (I Will Understand)," dedicated to her first child, Sean Preston, who was born in September. In November 2005, Spears released her first remix compilation, "B in the Mix: The Remixes."
