Once during the shoot, they dropped in to meet director Imtiaz Ali and saw Nargis. Not knowing that she was the actress, they told Imtiaz that such a khubsoorat ladki should be in Bollywood.
Much to their amusement, Imtiaz called out to her and introduced them to her as the lead actress of the film!
While the Kapoors went laal laal with embarrassment, they had no idea that later their son will be linked to the same girl. Papa ki pasand, bete ki pasand.
