AE DIL HAI MUSHKIL didn't affect bond between Karan Johar and the Bachchans. Proof:
News reports were rife few days back that Jaya Bachchan had a problem with her daughter-in-law Aishwarya Rai Bachchan’s intimate scenes in Karan Johar’s AE DIL HAI MUSHKIL.BIG B, JAYA, ABHISHEK AMONG OTHERS AT ABU JANI AND SANDEEP KHOSLA'S FASHION SHOW EVENT PHOTO GALLERY
Adding fuel, it was even being reported that Aishwarya is staying away from the movie as much as possible (you obviously would know that Aishwarya did not promote the movie to the level which Ranbir, Anushka and Karan did).
However, now Karan was spotted enjoying a fashion show with Amitabh, Jaya and Abhishek Bachchan.
More so, Shweta Bachchan Nanda walked the ramp. Hence the event would surely be special for all the Bachchans and Karan being invited to the event itself proves that there possibly is no rift between him and the Bachchans.
