Priyanka Chopra is the cause for chaos:Cinejwala:

There has been much hullabaloo over Shah Rukh Khan’s talked about promotional visit for ‘Don 2’ to Patna which was earlier cancelled but was rescheduled on the star’s insistence. While last time it was Shah Rukh’s presence that created a chaos, this time around it was his on screen lady love Priyanka Chopra who was the reason behind the confusion on trip.

She decided to board SRK’s charter flight at the last moment first to surprise her ‘Don’ and secondly to visit the town where she has her family roots. Priyanka’s mother’s
family resides there, hence she has some fond memories of the place and she didn’t want to miss the opportunity. However her decision became a cause for the high voltage confusion as there were too many untimely arrangements that had to take place.

There was a lot of chaos at Lucknow airport as there was frenzy amongst the people when the news of her arrival came. In her justification, Priyanka quoted “Patna is my city. My mother's family lives here. I just had to come.”
