"Express" is a song recorded by American singer Christina Aguilera for the accompanying soundtrack album to her film Burlesque (2010).
[7] "Express" was premiered on the On Air with Ryan Seacrest radio show (KIIS-FM) on November 3, 2010 as a promotional single from the album.
[13] Lyrically, the song evokes sexual theme, as she "seductively" sings, "Show a little leg, you gotta shimmy your chest".
[12] Blogcritics thought that "Express", among with "Show Me How You Burlesque" are the two songs that "work better in the context of the movie, where the elaborate visuals help distract from their lack of melody and strong hooks".
[13] An online website, Movie-Moron was positive toward the track, saying that it is "the most modern sounding thing" in the soundtrack, also compared "Express" to Aguilera's 2002 single "Dirrty".
[15] Jamie Tabberer of the Attitude magazine named "Express" a "glam big band number", and ranked it among the best songs ever recorded by Aguilera.
Aguilera performed "Express" for the first time at the American Music Awards of 2010 on November 21, 2010, held at the Nokia Theatre in Los Angeles, California.
[25] Wearing a "black spangly bodysuit" with knee-high boots and a bowler, Aguilera seated in a chair with her back to the audience in the beginning of the show.
[28] The video was met with controversy, with Billboard magazine questioning if "the kid's parents filmed his sexualized dance routine and uploaded it to YouTube".
