There have been others who have ended their friendships on a sour note. One famous example was when Aishwarya and Rani fell out after Ash got replaced by the Mukerji babe in 'Chalte Chalte'.
The Priyanka-Kareena and the Kareena-Esha Deol friendship also didn't stand the test of time.
There have been more cat fights than girl bonding between two female celebs in Bollywood. Of late there is a buzz that Katrina Kaif and Preity Zinta have struck up a friendship.
Katrina who's considered wooden and cold by many and doesn't have too many females liking her in B-Town says that she absolutely adores Preity Zinta.
Apparently the duo take time out of their busy schedules to chat, shop and hang out with each other.
Katrina has said, "Preity is such a warm and lovely person."
And she goes on to talk about why people think that two actresses can't be friends and so on.
It's just that no one takes the 'best-friends-forever' status of actresses seriously. Past experience can make anyone not want to do that.
We really doubt that this wooden actress would prove us wrong in the future.
