It was Sajid Nadiadwala who first bought the rights to make a film on the book '2 States'. 

Karan Johar had approached Sajid to be his partner in the film. And now that the film has done extremely well, Sajid is very proud to be associated with the film from the very beginning and for the longest time.

The response of the film has been so good, that it surely calls for a huge celebration.

However, the celebration of '2 States' is totally incomplete if Sajid, who has spearheaded this successful project wouldn't be here.

So, KJo has called Sajid to congratulate him on their triumphant partnership as well as to specifically mention how the success party of '2 States' will not happen till he is back from Poland, where he is currently shooting his next film, 'Kick' with Salman Khan.

Sajid confirms the news and adds, "Karan did call me and told me that the party won’t take place till I am back."
