Circus is the sixth studio album by American pop singer Britney Spears. Jive Records, in collaboration with Zomba Label Group and Sony Music Entertainment, released it on November 28, 2008. Having moved over 505,000 copies in the United States in its first week, Circus debuted on the Billboard 200 at number one, making it Spears's fifth number-one album. The feat made Spears the only act in Nielsen SoundScan history to have four albums debut with 500,000 or more copies sold.
The first single, "Womanizer", became Spears's first number one single on the Billboard Hot 100 since her debut "...Baby One More Time", almost 10 years prior. The second single, the title track of the album, "Circus", debuted at number three on the Hot 100 chart.
