"Lady Marmalade" — featuring Christina Aguilera, Lil' Kim, Mya, and Pink — was appeared on the 2001 movie Moulin Rouge's soundtrack. "[Patti] Labelle's original version was a song we had all loved growing up, and we saw it as a kind of honour to put our own spin on it," Missy, who co-produced the song, told Cosmopolitan in March while celebrating the 20th anniversary. "We wanted to showcase each of the 'four badass chicks from the Moulin Rouge,' bringing together their different skills and personas into a true celebration of diversity, talent, and female unity."
