After giving a scintillating performance in 'The Dirty Picture' Vidya Balan is all ready with her next movie 'Kahaani'.

Ever since the trailer of her film Kahaani has come out, there is a lot of positive buzz about Vidya Balan and the film. The actor seems to have sunk her teeth into an author-backed role, where she plays the role of a pregnant woman who is searching for the father of the child that she is carrying.

Vidya Balan looked radiant in a green and brown Sabyasachi Kalidaar dress at the music launch of her upcoming film Kahaani at the ongoing Kala Ghoda Festival 2012 in Mumbai on Saturday February 11th, 2012. The music was launched at the steps of the iconic Asiatic Library – a location that has often served as the venue for performances by music stalwarts. "It was Viacom 18's idea to collaborate with the on-going Kala Ghoda festival.

The crowd went berserk when Vidya Balan showed up on the stage and started screaming 'Ooh la la' – a song from her last film, The Dirty Picture. She flagged off the event with a 'dhunuchi' dance, an integral part of the Durga Puja festival. It was followed by the song, Piya Tu Kaahe Rootha Re, by Javed Bhashir, the second song on the Kahaani album.

After Vidya, director Sujoy Ghosh took to the stage and expressed his gratitude for those who were present. "I'm honored to release my film's music in the presence of such talents," said director Ghosh.
