On the sets of the song ‘Badtameez Dil’ in ‘Yeh Jawaani Hai Deewani’, Ranbir Kapoor and his director-friend Ayan Mukherji were spotted enjoying their time at the shoot. Ranbir insisted that after they were done shooting the song that Ayan should come forward and let Ranbir spray out champagne on him. Speaking of champagne, Deepika Padukone mentioned how Ranbir purposely sprayed more than three bottles of champagne on her; maybe if Sonam Kapoor was there with her, she would have gotten her answer. Kalki is also seen in this song and I must say, she has danced brilliantly.
