Prachi Desai will do a Bobby (a la Dimple Kapadia) for her next, Once Upon A Time In Mumbai.

Says a source, "In the film, Emraan Hashmi plays a gangster based in Dubai, who's obsessed with Dimple Kapadia.

In the film there's a song where Emraan and his girlfriend (played by Prachi Desai) watch Bobby and then Emraan gifts her Dimple's outfit.

It's a passionate sequence which has Emraan and Prachi getting drawn to each other. Initially, the demure Prachi was reluctant to wear the bold outfit but the director Milan Luthria managed to convince her."

Prachi, says, "Emraan's called Shoaib in the film. I play his conservative Muslim girlfriend Mumtaaz. Bobby was a big hit at the time the movie was set in. Shoaib is inspired by multiple real life personalities and one of them had a fascination with Dimple's Bobby persona. Hence Emraan is seen gifting me outfits due to his fascination with Bobby."

Prachi says she was initially hesitant, "Dimple looked so gorgeous that I didn't want to be compared to her but Milan convinced me. In fact, Milan gave us a month to work on our bodies for the song. While he wanted Emraan to flaunt his six-pack in the song, he wanted me to tone down my body."

She adds, "The scenes were shot over few months. Emraan is one of my fav co-stars and I am most comfortable with him. I was clear we wouldn't kiss, though."
