Sonam Kapoor's light moment on Dilli 6 set

One of the most anticipated films of this year is Rakeysh Omprakash Mehra's Dilli 6 starring Abhishek Bachchan and Sonam Kapoor in lead roles. While not much is known about the film or its premise, we came across this interesting picture sent by a surfer where director Rakeysh and Sonam share a light moment on the sets of the film.

Wonder what Sonam is giggling about? Maybe they were planning to pull a prank on AB Jr. What say?
