The song titled 'Heroine Hoon Main' is said to have been styled along the same lines as the Renee Zellweger musical. Set in 1920s Chicago, the US film tells the story of Velma Kelly, who makes a bid for fame after committing a murder.
A source told the Hindustan Times: "Kareena is clearly inspired by the Western musical here. The costumes, props, set pieces, lighting and the swaying dance moves, just about everything in the choreography of this song is on the same lines as that of Chicago."
The film's director Madhur Bhandarkar said he drew on Western musicals to create a distinct world for Kapoor's character to inhabit when shooting the song.
"Films like Chicago, or for that matter Moulin Rouge, are textbooks when it comes to Western musicals. I wanted to lend a distinct touch to 'Heroine Hoon Main' which would arrive with the credit rolls. After 'Halkat Jawaani', we have created an altogether different world for Kareena," he said.
The song has been described as "classy", while the earlier release 'Halkat Jawani' is designed to appeal much more to the tastes of a mass audience.
A source said: "The song is titled 'Heroine Hoon Main' and Kareena has never looked more stunning than this. In fact, this is the most uninhibited Kareena that one has seen on the big screen. Expect audience fantasies to go wild as the song is in an altogether unexplored and different zone. While 'Halkat Jawaani' was massy, 'Heroine Hoon Main' is classy."
Charting the rise and fall of fictional Bollywood actress Mahi Arora, Kapoor recently claimed that Heroine draws on the real lives of several Bollywood actresses.
The film, which releases on September 21, has been awarded an adult certificate.
