he Femme Fatale Tour was the eighth concert tour by American recording artist Britney Spears. It was launched in support of her seventh studio album Femme Fatale (2011). It was officially announced in March 2011, with dates for North American venues revealed. The tour was initially planned as a co-headlining tour with Enrique Iglesias, but he canceled only hours after the announcement. The show is inspired by the concept of the femme fatale and femmes fatales throughout the ages. The setlist was mostly composed of songs from Femme Fatale, although Spears also performed hits from her previous albums for her fans. Fashion designer Zaldy Goco created the costumes. In July 2011, Spears announced plans of playing a South American leg in territories she either had never been to or had not played for a long time. Spears has named the Femme Fatale Tour the best show of her career.
3ality Digital filmed a special of the tour during the Toronto shows in August 2011 in 2D and 3D. The special, titled Britney Spears Live: The Femme Fatale Tour, aired on Epix in the United States. BBC Worldwide acquired the rights to both 2D and 3D versions outside the United States.
