Emraan Hashmi who stars with Vidya Balan in the upcoming Ghanchakkar refuses to divulge details of their lip lock in the film, out of respect for UTV's head honcho Sidharth Roy Kapur, who's married to Balan.

​"I have promised myself that for this film I will not answer this question. Siddarth, Vidya's husband, is the head of this production house. If I want to do more films with them, then let's not talk about it," said Hashmi to reporters at the promotional event of Ghanchakkar earlier today (30 May 2013).

Balan, who plays a Punjabi woman for the first time, says she took training to get the Punjabi accent, in order to make the character as authentic as possible.

"I took training to get the Punjabi accent. I first learnt gaalis and that's the easiest way to learn any language. The character was so loud that I didn't want the character to pull me down," she said.

Directed by Rajkumar Gupta, Ghanchakkar is slated for a June 28 release.
