Why was Karan Johar hitting Ajay Devgn?

Not long ago KJo had a tough time dealing with the news of him paying Kamaal R Khan 25 lakhs to badmouth Shivaay! Now buzz is that a Miffed Karan Johar forced AIB to remove their tweet poking fun on Ae Dil Hai Mushkil. Karan Johar's upcoming movie Ae Dil Hai Mushkil faced a lot of heat recently after social media went berserk noticing how the opening riff of Bulleya was copied from the song Last Resort. Well, AIB did what they do best, captured the idea in their own unique fashion but what they did not see coming was that KJo might not like it.
