Femme Fatale Tour was the eight 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 femme fatales throughout the ages. The setlist was mostly composed by songs from her Femme Fatale album, although she included hits from previous albums for the 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 from her career.
