When Ranbir got Aditya, Kalki drunk: While shooting for one of the scenes in Yeh Jaawani Hai Deewani, Ranbir Kapoor replaced the water in a couple of shot glasses with real vodka. A song sequence required Kalki Koechlin and Aditya Roy Kapoor to drink from shot glasses. As is the usual norm, water was poured into the glasses. But Ranbir decided to replace the water with actual vodka. Both his co-stars were left quite shocked. But once they realised Ranbir’s prank, Kalki and Aditya apparently doubled up in laughter.
