when i first saw zarine's pic (the only pic which was available before veer's promos) i was like she doesnot luk like kat at all...she luks more like amna sharif.....but after watching veer's promos i had to change my statement since she does luk like kat a lot....the only difference is that kat is thinner than her and and kat has a longer face than her...ofcourse u will be abe to tell which one is zarine and which one is kat....but if i am told they r sisters, it wont surprise me at all.....
