The first in this list would probably be Shah Rukh Khan slapping Farah Khan’s husband Shirish Kundar! The choreographer-turned-director then was going through a rough patch with Shah Rukh khan, though they happened to be thick friends earlier. Shirish Kunder had said something unpleasant to which the actor had slapped him in public! This is old news, but it still haunts. Recently there is also a rumour that he slapped singer Honey Singh over some hot exchange of words.
