Kangna Ranaut's character was inspired from the life of model Geetnajali Nagpal who was suffering from a mental disorder and was found begging on the streets of Delhi.
The scene of Kangna Ranaut's outfit falling in the middle of a ramp show was inspired by the 2006 Lakme Fashion Week in Mumbai where Carol Gracias halter top slipped off, exposing her breasts.
The film received many awards in the Best Actress category for Priyanka Chopra and Best Supporting Actress for Kangna Ranaut, most notably in Flimfare Awards and National Award.
Priyanka Chopra's character was inspired by Alicia Raut.
The director Madhur Bhandarkar wanted to end the movie where the character Meghna Mathur gets pregnant and decides to flaunt her pregnancy, but the actress Priyanka Chopra had reservations about that as she felt that it would portray a negative image among her fans, so Madhur had to re-write the script. He also extended the role of Sonali (Kangna Ranaut) to meet the script requirements
Madhur Bhandarkar: Plays himself as a movie director who "must be doing research for a real-life based movie". One of the models is shown passing a snide comment at him that he "won't leave even the fashion world alone."
