Britney Spears produced a mini-tour for the House of Blues under the name "The M+M's", with 6 shows altogether, she sang live during some lines of her songs. She recorded her latest album with producers such as Sean Garrett, J. R. Rotem and Nate "Danja" Hills throughout 2006 and 2007.The release of Spears's fifth album, Blackout, was rescheduled to 30 October 2007 rather than November 2007 due to online leaks.Blackout debuted at number two on the U.S. Billboard 200 charts.It was fairly well received by critics. Rolling Stone gave the album 3.5 out of 5 stars, stating that "Blackout is the first time in her career that she's voiced any real thoughts about her life. The old provocation game is still afoot, but Britney's stubbornly holding on to her freakness — it's the only form of rebellion she's got left." All Music Guide also rated the album 3.5 out of 5 stars, calling Blackout "coherent and entertaining" and stating that "it holds together better than any of her other records." Blackout's first single, "Gimme More" debuted worldwide on August 30.The song, which was Spears's first produced by Danja, peaked at number three on Billboard's Hot 100 on October 3, making it her most successful single in the U.S. since her debut, "…Baby One More Time".Spears's highly-anticipated performance of "Gimme More" at the 2007 MTV Video Music Awards was panned as a disappointing attempt at a comeback. The BBC stated that "her performance would go down in the history books as being one of the worst to grace the MTV Awards", and The Times noted that "Spears was out of synch as she lip-synched and at times just stopped singing altogether."Despite the criticism on her performance, the single has achieved worldwide success.Source: wikipedia
