Britney Spears - Piece of Me (glamour slideshow) HD

Blackout is the fifth studio album by American recording artist Britney Spears, released on October 26, 2007 by Jive Records, four years after her previous studio album In the Zone. Spears started writing songs for the album in November 2003, and began experimenting with a more acoustic sound. Following her marriage with Kevin Federline in 2004 and the birth of her first son the subsequent year, she begun recording the album in 2006 with producers J. R. Rotem, Danja and Kara DioGuardi. She gave birth to her second son and filed for divorce in late 2006, after which she continued working with producers such as The Clutch and Bloodshy & Avant. In May 2007, she embarked on The M+M's Tour at House of Blues venues across the United States.

Recording sessions took place at various studios around the country, including at Spears' home in Los Angeles. Some of the producers claimed to be impressed with her work ethic and professionalism, despite all her problems in her personal life. Spears wanted to make a fun, danceable album with uptempo, high-energy music. Blackout is mainly an electropop and dance album, which incorporates elements of several musical genres such as funk, Euro disco and dubstep. The themes of the album range from fame, sex, love and dancing. The cover sleeve and images were shot by Ellen von Unwerth. The centerfold pictures, which feature Spears and a priest in suggestive poses in a confessional, were condemned by the Catholic League.

Blackout was to be released on November 13, 2007, but it was moved up to October 30 due to unauthorized leaks. Zomba Label Group sued Perez Hilton for posting at least ten leaks on his gossip blog; the parties reached a settlement in June 2009. Blackout received mostly positive reviews from music critics. Most called it her most progressive and consistent album yet, but others argued that its quality should have been attributed to the producers rather than Spears, and also criticized her vocals for being overly-processed. Blackout was set to debut at the top of the Billboard 200, but debuted at number two due to a last-minute rule change. The album topped the European Top 100 Albums and the Canadian and Irish charts, while peaking inside the top ten in another thirteen countries. By the end of 2008, Blackout had sold 3.1 million copies worldwide.

Three singles were released from the album. "Gimme More" reached number three on the Billboard Hot 100 and became a top-five hit in fourteen countries. "Piece of Me" reached the top-ten in twelve countries, including Australia, Canada and the United Kingdom. Unlike her previous albums, Spears did not heavily promote Blackout. Her only performance to promote the album, "Gimme More" at the 2007 MTV Video Music Awards, was universally panned by critics. In subsequent years, reviewers have viewed the album in a more favorable light. Blackout has appeared on reader polls by Billboard and Rolling Stone, while The Times named it as the fifth best pop album of the decade. In 2010, Rob Sheffield of Rolling Stone called Blackout "the most influential album of the past five years."
