Spears's performance at 2007 MTV Video Music Awards received much media attention and was lauded as her "comeback".She performed "Gimme More", the lead single from her upcoming album. Reviews of the performance were unfavorable; BBC's David Willis stated that "her performance would go down in the history books as being one of the worst to grace the MTV Awards," and Times Online noted that "Spears was out of synch as she lip-synched and at times just stopped singing altogether<(WHATEVER) ."However, this did not stop the single from becoming a worldwide success.
