The otherwise slim and trim Jacqueline Fernandez has a rather uphill task awaiting her. The actress has to put on around eight to 10 kgs for her upcoming film

The actress sports a de-glam look in the film.

A source says, `Jacky had been attending workshops for the last two months to prep for her role. She has stopped going to the gym and is eating a lot. She has let go of her diet regime and is gorging on desserts and fast food.`


Jacky, who will star opposite Salman Khan in Sajid Nadiadwala's film, has already left for London where it is being shot. Khan will follow suit shortly.

The actress' spokesperson confirmed the story.
