/> It's stand-up comedian and Badmaash Company actor Vir Das who quietly shot a special music-video with choreographer Farah Khan for Imran Khan's uncle Aamir's production Delhi Belly on Feb 23.

Farah Khan who left for Chandigarh for a month-long schedule of her husband's directorial venture Joker, wrapped up the Delhi Belly song for Aamir and then headed for the cool climate of Chandigarh where Shirish Kunder shoots in the open fields for Joker.

Farah said before leaving, "Aamir's song is in Mumbai. Then I leave with my babies and their maids for Chandigarh for a month for the Joker outdoors.I'm looking forward to taking my three babies to Chandigarh in pollution-free outdoors, not to mention the great food!"

As for the song why is it not being shot with Imran? According to a source, "When Aamir decided to do a music video for Delhi Belly he was very clear it would be filmed on Vir Das and not on Imran.When it comes to doing what is right by a project, Aamir is unflappable."

Delhi Belly director Abhinay Deo appears blissfully unaware of the extra song and dance for his film.When asked about it he remained tightlipped.Abhinay has long moved on to another producer Ritesh Sidhwani and another film Game.
