The sexy siren is all set to dance dirty at the music launch of the film.

The first look of the movie ‘The Dirty Picture’ revealed an otherwise girl-next-door Vidya Balan’s ravishing and sexy avtaar. While the trailer was an instant hit among the masses, the song Ooh la la has become a popular bollywood number and is hummed by many.

Taking advantage of the popularity of the song and Vidya’s new sizzling avtaar, the makers of the film have now decided to go live among the audience with the music launch of the film. While most of the film related events are meant for the media, the makers of The Dirty Picture have decided to make it free for all public.

What’s more exciting is for the first time ever, Vidya will be seen performing live in public on the song Ooh La La. It may be recollected that the actress has never performed for any award functions or stage shows till date, in spite of receiving several offers.

“The general public has been invited at large to attend the event with friends and family to kick off a 'dirty' weekend. Also Vidya Balan will be performing on the 'Oh La La' number from the film”, confirms a source.

The source went on to add further, “Vidya and the other lead cast of the film will be seen in the same flamboyant outfits they are sporting in the film. The dazzling show will recreate the colorful 80's era and feature live performances by the film's stars and singers”.

The music launch will happen at The Inorbit Mall, Malad in Mumbai on Friday, November 4 evening.
