Not many of us know that Sonakshi Sinha, who is known for her demure village belle image, can whistle too. So much so, that director Ashvini Yardi and Sonakshi's co-star in Son Of Sardar Ajay Devgn decided to include her whistling-act in a song from their upcoming film.

A source close to the team said, "While she was taking a break from the shoot, Sonakshi took us by surprise with her bindaas whistling skills. The entire team immediately decided to put her seeti scene in a song that consists of a dream sequence. It was a perfect fit for the fun loving character she plays in the film."
