Sonakshi Sinha has started toning up for her role in Joker in which she co-stars with Akshay Kumar.
According to Mid Day, Sonakshi is training under Yasmin Karachiwala at her fitness centre in Bandra.
Yasmin helped Katrina Kaif get in shape for her Shiela Ki Jawani item number in Tees Maar Khan (TMK) and has in the past worked with Kareena Kapoor, Imran Khan, Karisma Kapoor and Kunal Kapoor.
Sonakshi shed a lot of weight for her role in Dabangg, but remained short of being svelte. Since then she has regained some of her lost weight.
"Sonakshi has to knock off inches for Joker. Her role demands a fit and toned body. She has begun her workouts with Yasmin as preparation for the movie," a source tells Mid Day.
Joker is being directed by Shirish Kunder, husband of Tees Maar Khan director Farah Khan. Touted as Bollywood's first 3D action film, it has been in the works for four years.
Akshay Kumar who is co-producing the film says it will "be one of the most technically advanced movies made in India."
"The story moves from a village to NASA and well after that there's some suspense involved."
