Spears first performed "Gimme More" at the 2007 MTV Video Music Awards on September 9, 2007, wearing a black, jewel-encrusted bikini. The performance was panned by many critics, who commented extensively on her "singing", dancing and wardrobe, with one deeming it as "one of the worst to grace the MTV Awards". On September 10, 2007, Chris Crocker uploaded a video on YouTube in response to the criticism titled "Leave Britney Alone!", which made him an Internet celebrity and attracted attention from the media. Spears has also performed "Gimme More" at the Femme Fatale Tour (2011) and (2013). "Gimme More" has been covered and sampled by many artists, including Miley Cyrus, Sia, Marié Digby, and Slayyyter.
