"I don't believe in size zero. Yes, I have lost weight as I am training myself for my next film. I am working hard to build muscles for my character, which is inspired by Mary Kom," said Priyanka.
The 30-year-old actress, who doesn't shy away from shedding glamorous image to try different characters as she did in 'Kaminey' and 'Barfi!', finds the journey of Mary Kom, a girl from Manipur who went on to become five-time world champion, inspiring.
"It's not a biopic but it is a film, which is inspired by her life. I personally find her journey very inspiring. This film talks about how to grab the right opportunity, work hard and how sheer hard work can bring success. I am very nervous about the film as it is very close to my heart," Priyanka said.
To be directed by Bhansali, the film will go on the floors by June.
The 30-year-old Mary Kom was honoured with Padma Bhushan, India's third highest civilian honour, this year.
