Circus is the sixth studio album by American recording artist Britney Spears. The album was first released on November 28, 2008 by Jive Records. Spears started work on the album in early 2008 with a range of producers including long-time producers Bloodshy & Avant and Danja. The album consists of electropop and dance-pop.
The album received positive reviews from critics and drew heavy comparisons to her previous studio album Blackout (album). Commercially the album also performed very well. In the United States the album debuted atop the Billboard 200 selling over half a million copies and 814,000 copies worldwide in first week. The feat also earned Spears a place on the Guinness Book of World Records due to Spears becoming the youngest female artist in history to have five number one albums. Elsewhere the album had a good commercial response topping charts in Canada and the European charts.
The album's lead single "Womanizer" became a worldwide hit and broke records for registering the largest jump to number one on the Billboard Hot 100 after debuting at number ninety-six on the chart. The song became her best-selling single in the US since her debut single "...Baby One More Time". The second single "Circus" debuted and peaked at number 3 in the US. The third single "If You Seek Amy" created controversy for its double entendre, but managed to peak at number 19 in the US. Circus is Spears' second album since ...Baby One More Time (album) to have two top-ten hits and three top-twenty hits. The album gained a Grammy Award nomination for Best Dance Recording for "Womanizer," but lost to Lady Gaga's "Poker Face." The album has become her biggest-selling album since In The Zone (album) selling over eight million combined sales of digital tracks and over four million copies worldwide.
Spears embarked on her fifth concert tour to support the album named The Circus Starring Britney Spears. The tour kicked off on March 3, 2009 in New Orleans' New Orleans Arena and finished in Adelaide's Adelaide Entertainment Centre. Spears embarked on four legs of the tour visiting North America twice performing elsewhere in Europe and Australia. The tour gained controversy in Australia due to accusations of lip-synching. Elsewhere Spears promoted the album, performing on several television shows and releasing a promotional music video for the track "Kill The Lights".
