Her oomph and chutzpah in the ‘Ooh la la’ song from ‘The Dirty Picture’ is already a rage. Vidya Balan is now gearing up to mesmerise fans with a live performance with other artists at the music launch of the film in Mumbai on Friday. "Vidya, Emraan (Hashmi), Naseeruddin Shah, Tusshar Kapoor, Bappi Lahiri and Shreya Ghoshal will perform at the event live," Girish Johar, head of acquisition and distribution, Balaji Motion Pictures, told the media.

Asked if Vidya will perform to ‘Ooh la la’, Johar said: "Yes of course!!!" The event is to be held at the Inorbit Mall in Malad, starting 6 p.m. It is free for everyone. "That's the novelty value. We wanted to take the film to the public directly so that they can interact with the stars and enjoy the music," he added.

The actors themselves are quite excited about the colourful music launch. Tusshar tweeted: "Hello people, on Friday, 4th Nov, pls come to 'The Dirty Picture' audio launch. It's at 6 pm at Inorbit, Malad and free for the public. It should be a first-of-its-kind audio launch where you will witness live performances by the star cast and singers. ‘The Dirty Picture’, produced by Ekta Kapoor, chronicles the rise to fame, gradual fall and death of southern actress Silk Smitha. The film is releasing on December 2.
