"Blackout" was originally scheduled to be released on November 13 in the United States, but was rush-released after being leaked online. The album received positive reviews from music critics, some of whom described it as Spears's most progressive and consistent album. It debuted at number two on the US "Billboard" 200 with first-week sales of 290,000 copies. By the end of 2008, "Blackout" had sold 3.1 million copies worldwide. The singles "Gimme More", "Piece of Me", and "Break the Ice" peaked at number 3, 18, and 43 on the "Billboard" Hot 100 respectively. Unlike her previous albums, Spears did not heavily promote "Blackout"; her only televised appearance for "Blackout" was a universally panned performance of "Gimme More" at the 2007 MTV Video Music Awards. However, many of the songs of "Blackout" were performed on her tour The Circus Starring Britney Spears in 2009, the Femme Fatale Tour in 2011, Spears's concert residency in 2013–17, the in 2017, and the Piece of Me Tour in 2018.
