The 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 femme 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. 　　The tour, divided in five segments, portrays a story in which Spears is a secret agent, who is chased by a stalker named Tormento Lancie; played by Rudolf Martin. The first section features her escaping from prison along with other female inmates. The second segment displays upbeat dance numbers and ends with a performance inspired by Marilyn Monroe. The third section features an Egyptian theme with fireworks and acrobatics. The fourth segment displays energetic routines and motorcycle costumes. The encore begins with a video interlude of Spears capturing the stalker, and is followed by two performances in which she defeats a group of ninjas.
