"Now off to my first meeting with the one and only Mary Kom! Dhan tana... Will make her teach me how to wear my boxing gloves," Priyanka tweeted Tuesday night.
The 30-year-old will be portraying the five-time women's boxing champion in Sanjay Leela Bhansali's film.
It is also said that Mary Kom herself might also make a special appearance in the film, as the opponent of the on-screen Mary Kom.
The movie, which will be directed by Omung Kumar, will go on the floors early next year.
