When size zero became a buzzword for Bollywood, actress Vidya Balan broke the stereotype around a conventional Bollywood heroine's look by proudly flaunting her curvaceous figure in Milan Luthria's directorial film The Dirty Picture.

As the film, which was based on the life of adult film star Silk Smitha, has completed seven years on Sunday, Vidya, who rose to a spectacular amount of fame for the role of Silk, became emotional and penned a heartfelt post on the Instagram saying, the film changed her life forever.
