Raj Kumar Gupta worked with Vidya Balan for the first time in "No One Killed Jessica" when the actress was unmarried. They teamed up again for "Ghanchakkar" and the director praises the "Parineeta" girl for not "limiting herself" even after marriage.

"Vidya is a thorough professional. She doesn't limit herself as an actress even after her marriage. She does whatever she is asked to do," Gupta told IANS.

There were reports that the film has a kissing scene between Vidya and Emraan Hashmi, but Gupta refused to confirm it saying: "As far as the lip lock scene is concerned, I won't say whether it is there or not. All I can say is they play husband and wife, so there is a space to explore."

Gupta, who is directing a comedy for the first time after grim and gritty "Aamir" and "No One Killed Jessica", said: "It is a situational comedy and I want to explore myself as much as I can."

He admits it is "not easy to direct a comedy film".

"Ghanchakkar" is slated for a June 28 release.
