This is a single by American pop singer Christina Aguilera from the soundtrack to the film Burlesque. The singer co-stars in the movie along with Cher and "Express" is about her character's life as a burlesque dancer. The tune is one of eight songs Aguilera wrote for the soundtrack.
Aguilera's performance of this song on the final of the UK prime time program The X Factor received thousands of complaints. Viewers rang in upset at the singer's raunchy routine, which was viewed by several million children and their families. Aguilera defended her presentation at the UK premiere of Burlesque, saying: "I don't think there is such a thing as too raunchy when it comes to the art form of burlesque. It's very empowering to women to feel confident in their own skin and in their bodies and this represents that. Everyone in the spotlight is judged and there are many opinions out there, but I stick true to what I believe in."
