The leading ladies of the movie, Once Upon A Time In Mumbaai -- Kangna Ranaut and Prachi Desai -- arrive at producer Ekta Kapoor's residence to celebrate the film's success, in Mumbai on Wednesday.

The film opened to rave reviews and is on its way to becoming a runaway hit at the box office.

Close on the heels of the women were the film's leading men -- Ajay Devgn and Emraan Hashmi who pose for this picture with the film's director, Milan Luthria.
