Katrina trying to avoid Ranbir?

Ranbir Kapoor and Katrina Kaif, who turned into the best of friends on the sets of Ajab Prem Ki Ghazab Kahani, have suddenly lost all the warmth they had for each other. The two of them have been cold-shouldering each other recently.

A few days ago, at Future Works Studio, both of them were shooting for Prakash Jha"s Raajneeti. Apparently, the two stars were clearly trying to avoid each other. They only interacted when they had to shoot some scenes together. But once the filming was done, they were in no mood to talk to each other.

Though this piece of news may bring happiness to some, one can"t help but wonder what happened to the camaraderie the stars shared? Could it have something to do with Ranbir"s friendship with Priyanka Chopra? Guess only Ranbir and Katrina can tell.
