Challo Dilli co-producer Krishika Lulla reveals Lara Dutta's professionalism during the shoot of the film.

She says, "Lara plays a socialite in the film while Vinay Pathak an obnoxious guy from Delhi. It's a story set in small towns and often we would stop to shoot at roadside dhabas on the highways.

Initially, Lara was hesitant but later, she became cool about shooting everywhere. In Jaipur, we forgot our diet and ate oily food.

Once while shooting at a dhaba, Lara had high fever and it was freezing cold but she did her shoot without any fuss." Lara's co-producer, too, did you expect anything less?
