So much so that she shies away from doing 2-heroine films, like Anurag Basu's Barfee recently.
In fact she has said no to several plum assignments in the past because she didn't want to be pitted against another female actor.
But Kalki Koechlin has been an exception.
Contrary to reports Katrina Kaif and Kalki Koechlin, the two ‘Ks' studies who have just done a film together Zindagi Na Milegi Dobara, have a lot in common and get along like a house on fire.
Kalki, we must remember, stepped into a part originally earmarked for Katrina in Dibakar Bannerjee's Shanghai. That didn't stop them from becoming friends.
They both pooh-pooh reports that they had a tough time bonding together.
Does Kalki feel Katrina has hogged all the limelight in the publicity for ZNMD.
Kalki wonders who is spreading these rumours. "On the contrary Katrina and I get along very well. She's relaxed and level-headed, " she says.
Katrina is even more vocal in her denial of any stress between the two, "It is considered almost inevitable for two actresses to fight when they're working together.
But those who're looking for a spicy fight between us are just barking up the wrong tree. Me and Kalki got along very well. Sorry to disappoint some people. But me and Kalki get along just fine. "
As for Katrina cornering all the publicity she observes pragmatically, "This is not a film about one actor. It's an ensemble cast, like Farhan's Dil Chahta Hai and Rock On. We're all equally important. "
