The song has been downloaded by people who believed it was part of the official soundtrack to Shah Rukh Khan's next release.
The film's publicist issued a statement saying: "There is a fake song claiming to be from Excel Entertainment's forthcoming Don 2 doing the rounds on the internet and because of the popularity that the film and character has amongst the audiences, fans are downloading the song as they think it's from the film.
"Please note that the song is not from the film and someone is just using it to publicise that particular song.
"The Don 2 soundtrack will be released in the market shortly and there will be an official communication in that regard."
Don 2: The Chase Continues centres on a crime lord's chief sidekick who finds himself being pursued by international drug squads.
Directed by Farhan Akhtar and starring Shah Rukh Khan, the film is due to be released on December 23.
Salman Khan reportedly refused to allow the trailer for Don 2: The Chase Continues to be shown before screenings of Bodyguard even though they are made by the same production house.
