The atmosphere on the set of Aaditya Dutt's 'Dil Diya Hai' turn nasty when Geeta Basra lost her cool as Emraan Hashmi plays a prank on her. "A fan came up to me for an autograph. He handed over a pen to me saying it was a gift from Emraan. As soon as I touched the pen, I got an electric shock. I was fuming and wanted to get back at him. So as soon as I got the opportunity, I emptied a bottle of water over his head," explained Geeta. But Emraan on his part takes no responsibility for the incident.
