Alia Bhatt, we hear, caused some chaos during the initial days of shooting for Humpty Sharma Ki Dulhania. A unit member tells us that she would fiddle with the microphone while sitting in front of the monitor and often say `pack-up'. After the confusion triggered by Alia's abrupt calls, the assistant directors were given an additional task - to keep the microphone away from Alia.

Interestingly, the actress, who's said to be fast with her make-up and dressing, would always report on the sets and announce, 'Okay, ready', while the team would still be preparing for the next shot.
