Ali Zafar unaware of 'who' Katrina is!!

It started with both Ali Zafar and Katrina Kaif being present at a party, where Katrina thought it would be nice to meet her future co-star. She went over to him and tried talking to a baffled Mr. Zafar who did not have a clue as to who she was! After such an incident a star would normally either be angry or upset, but Katrina took it rather nicely and introduced herself to Ali Zafar.
 
Later Katrina explained, that Ali was new and doesn't know everyone and that when she entered the industry she herself did not know anyone. Surprisingly, after having spent 4 years in the fraternity, she still doesn't know everyone!. 
 
Well, now we are sure Ali does know who Katrina is! And maybe, Mr. Zafar has also learnt the lesson to do a little research on his upcoming co-stars next time around!
