Mumbai, May 20 -- Deepika Padukone and Imtiaz Ali share a special equation. And we have come to know the actor has started work on a film project with the director without signing any official documentation yet.
Deepika, who has earlier acted in Imtiaz's directorial Love Aaj Kal (2009) and Cocktail (2012; co-written by Imtiaz), will be seen in his next, along with her ex-boyfriend, Ranbir Kapoor.
An insider says, "Deepika is doing the film with Imtiaz. When a director shares a great professional equation with an actor, they don't necessarily need official documents to start working on their projects. Imtiaz has had a few script discussions with her and she has always made time to attend all the sittings and workshops."
While Imtiaz couldn't be reached for a comment, we have come to know that the film is likely to go on the floors by the end of the year. This is the first time after the 2013 hit, Yeh Jawaani Hai Deewani, that Deepika and Ranbir will be working together.
