Priyanka Chopra and Lara Dutta are both working in Faran Akhtar's Don 2. Priyanka is the leading lady of the film while Lara is playing the character that was played by Eesha Koppikar in Don part 1.
The shoot is going on in Berlin but insiders report that the two ladies are quite cold towards each other. They hardly have a friendly chat and nothing more than a hi or hello. They prefer to stay away from each other as much as possible. People say it is because Lara feels she has an unimportant role while Priyanka is the main leading lady in the project. Sources also say that Lara never wanted to work in the movie but is doing it because of Farhan and Shahrukh Khan recollecting an old update where it was said that SRK returned a favor to Lara by letting her have a part in Don 2 when she performed for one of his concerts when many other actresses refused.
Well, even if there is such a thing, there was once a time when Lara too was the main lead and Priyanka played a side role in her movie. It is also quite possible that this is just another made up story and the actresses are actually doing all fine. Remembering how we initially read that Rani and Vidya didn't talk on the sets of No One Killed Jessica and that Rani considered herself extremely senior and preferred to stay unapproachable. By the time, we saw the promotions and the final release the ladies seemed to have become quite close.
It always seemed that Priyanka and Lara were quite good friends thus, we can't really say if this is all very true till further updates.
