Christina Aguilera, Lil' Kim, Mya and Pink had a top-100 year-end Billboard single in 2001. Their recording of "Lady Marmalade" appeared at No. 24 on Billboard's Year-End Hot 100 Singles chart.
The song was made for the soundtrack of Baz Luhrmann's 2001 film Moulin Rouge! and reworked the 1974 hit by Labelle. Missy Elliott and Rockwilder helped produce the new version, giving it a polished blend of pop, R&B and hip-hop. The collaboration brought together four prominent artists from different corners of early-2000s popular music.
"Lady Marmalade" also topped the weekly Billboard Hot 100 in the United States and became one of the year's defining crossover singles. A common mix-up is confusing the song's year-end position with its weekly peak: No. 24 refers to its ranking across the entire calendar year, while its weekly chart peak was No. 1. The recording also became closely associated with the film's extravagant Paris nightclub sequence.
