Why Priyanka @ silent on RamCharan's Zanjeer?

Ram Charan 70-crore Bollywood project 'Zanjeer' has become point of discussion everywhere. Even though the unit already wrapped up the first schedule, there is still confusion on who is playing Cherry's love interest in the film. Did Priyanka Chopra really sign the film? If so, why she has been keeping mum?
Piggy Chops has the habit of updating everything about her films and future commitments on the social networking site. But, she has never written a single word about Zanjeer remake till date and spoke nothing about it in any of her interviews.
Media took into account the statement given by Apoorva Lakhia (director of 'Zanjeer' remake) in an interview that Priyanka has given nod for the project. Except that, there is not an official announcement from the film unit confirming Priyanka's presence in the film till now. The confusion over the female lead in this much awaited film will continue till the time 2nd schedule of the film kickstarts, as the combination scenes of Hero & Heroine will be shot then. Till then, let's not come to any conclusion!
