Says Aziz Mirza's daughter and creative director of KK, Rahila, "During the outdoor in Canada, Shahid decided to play a prank on Vidya, with whom he'd become good friends, during the shooting. Shahid discovered Vidya's weaknesses she is terrified of spooky stories."
One night, at 2.30 am, Shahid wore a horrifying mask and knocked on Vidya's door. Rahila continues, "The unit members collected to view Vidya's reaction but it was Vidya's mother who opened the door! Vidya and her mom were put up in a suite with a common door and Shahid didn't know that the actress was in the other room."
What happened next was a scene out of a comedy film. Continues Rahila, "It was hilarious! Vidya's mom didn't know it was Shahid behind the mask. She thought he was an intruder, so she held on to him tight and screamed for security. Of course everyone started explaining to Mrs. Balan that it was all Shahid's plan, and he'd taken everyone into confidence."
The next day Shahid and Vishal Malhotra, who plays Shahid's friend in the film and was part of the prank, were worried about facing mommy Balan. Says Rahila, "Shahid and Vishal were like schoolboys getting up every time Vidya's mom came near them. Of course she is quite a sport and laughed it off."
