According to an insider, "Katrina has been making entries in this diary for the last three months since she began shooting for New York. It's like her personal diary with inputs from John and Neil. It will cover all their experiences peppered with interesting anecdotes while shooting for the film in New York and Philadelphia. Katrina is very excited about it as she's never kept a diary before and this is a novel way of sharing her experiences, on and off screen, while filming."
The diary will also feature exclusive pictures by John and Abhishek. Says the source, "It's going to be a picture diary and will be revealed to everyone during the film's release. Like all things associated with Yash Raj, even this is very hush-hush. Neil and John have taken lots of candid, fun, and interesting pictures. John is quite camera-savvy and his pictures have shaped up well while Neil is still learning. Some contents of the diary will be published in a leading newspaper just a month before New York's release."
Katrina, who is currently in Mumbai for the promotions of Subhash Ghai's Yuvvraaj, says, "It's too early to reveal any details about the diary right now."
