"We will start the film in June. I am training for it at the moment and it will take me that much time to come into shape," she said at a press conference on Tuesday.
The actress also added that the training was rigorous.
"Every part of my body hurts. Now I know how Mary Kom trains herself everyday," she said.
The film will be directed by Omung Kumar Bhandula.
Priyanka will also be seen in the remake of Zanjeer, Gunday and Krrish 3 this year.
