PC & SHAHID in KUNAL's next A Period Love Story...

Their relationship might be on and off in real life, but Priyanka Chopra and Shahid Kapoor's reel life relationship is expected to last a century.

At least on screen. The couple has signed Kunal Kohli's next film, which is a love story chronicled over a span of 100 years.

While there is always speculation if Chops and Sasha are together or not, this seems to be an indicator that professionally they will be linked in the near future, regardless of their love life.

A source tells us, "This has a very different script dealing with the concept of eternal love. Priyanka loved the script the very moment she heard it and has accommodated her dates to shoot with her beau Sasha."

Kohli, who specializes in love stories, has slated the movie to go on floors in May.

The source adds, "Since it is a period film, spanning over 100 years, it becomes essential to have different get-ups and different locations with unique set-ups and backdrops.

Kunal has shortlisted various locations, but he will be paying a personal visit to each one to ensure that the locations fit into the script perfectly."

Kunal says, "I am currently doing a recce for the film. We have to zero down on various locations, as the movie covers 100 years."

Although Kohli has managed to rope in Shahid and Priyanka, he is yet to finalize the title of the film. He adds, "A period love story needs to have the correct title. I haven't finalised on any as yet. I would love some suggestions; it would certainly make it easier for me."

Previously Priyanka and Shahid were seen in Vishal Bhardwaj's Kaminey (2009). Let's see if they'll be able to rekindle the same chemistry again.
