Stars of Bollywood's upcoming film 'Barfi' - Ranbir Kapoor, Priyanka Chopra and Ileana D'Cruz, along with film's music composer Pritam Chakraborty, director Anurag Basu and co-producer Siddharth Roy Kapoor were recently present at Gurgaon to promote their film that is slated to release tomorrow. And it was here that the fans of Ranbir Kapoor compelled him to oblige to their requests. 

As Ranbir has lent his voice to the original song 'Fatafati' from the film, the fans there asked him to hum a few lines from the same number. And left with no other option, Ranbir had to give in the demands. However there's also another reason for his performance. 

The team was two hours late and hence Ranbir wanted to compensate for the delay. He did not only sing, but also apologized for arriving late.
