We had earlier reported that actress Sonakshi Sinha will be seen essaying the key role in an upcoming biopic on the life of Dawood Ibrahim's sister named 'Haseena'. After wrapping up the shoot of the action flick ' Force 2 ', the pretty lady will gear up for the biopic movie. Reportedly, the actress will have to undergo a lot of preparations for the film.

Sonakshi will have to put on a few kilos for the film as the role she is about to take up requires the effort. Haseena Parkar was far plumper in appearance than Sonakshi's current frame. So, the actress will have to put on weight to fit into the character. The pretty actress will also meet Dawood Ibrahim's relatives as a part of preparations. She is most likely to meet Haseena's daughters to understand more about their mother and to get her nuances right. The biopic is titled as ' Haseena - The Queen of Mumbai ' which is likely to go on floors next year.
