After the resounding back-to-back success of 'The Dirty Picture and 'Kahaani', Vidya Balan has signed her 'No One Killed Jessica' director Rajkumar Gupta’s 'Ghanchakkar'.

Unlike her characters of Sabrina Lal (in No one Killed Jessica), S'ilk (in The Dirty Picture) and Vidya (in Kahaani), Balan plays a housewife in Ghanchakkar.
