Kangana Ranaut is set for a brush with the underworld on screen once again after "Gangster". She reveals that her character in "Once Upon A Time In Mumbaai" is a cross between don Haji Mastan's wife Sona and yesteryears beauty Madhubala.

"In real life Haji was a big fan of Madhubala-ji and he fell in love with Sona who looked like her. So my character is a cross between the two, " Kangana told in a telephonic interview from Mumbai.

"The character I am playing has some similarities with Madhubala-ji...like the way she was a superstar and had problems in life..., " she added.

Talking about her character Rehana in the film, Kangana said: "Rehana is a very big star...she is the woman who evokes desire in everyone and then she falls in love with this gangster and discovers a new world. My character transforms from a star to a woman."

Her character might be similar to that of Madhubala but Kangana was inspired by other yesteryears heroines too for the role.

"I observed 70's actresses like Zeenat Aman and Parveen Babi... they were the rebels who wore bikinis and were style icons. My character is somehow like them, " said Kangana.

Set primarily in the 1970s Mumbai, the film by Milan Luthria will trace the changing face of the underworld through the eyes of a police officer. The story follows the rise of Sultan (Ajay Devgn), and his eventual fall when his protege Shoaib (Emraan Hashmi) challenges his supremacy and usurps power to rule the underworld in the city.

The film that releases July 30 also features Prachi Desai.

On her personal life, Kangana is candid and says she doesn't care what people think of her. And being a Bollywood diva is not really her cup of tea.

"I really don't care what people think of me and how they perceive me. That is okay with me because I don't make an extra effort to be friendly to people. I do things I like doing, " Kangana told.

"I'm a very moody person. There are times when I want to talk about my life whereas there are days I just want to be left alone, " she said.

Kangana is unlike other Bollywood stars who are interacting with fans on micro-blogging site Twitter but maintains she shares a "personal relationship" with her well-wishers.

"I don't put myself on Twitter to see how many people are crazy about me. I don't like to blow kisses at my fans to show that I am a diva. This whole idea of diva doesn't turn me on, " said Kangana.

"I share a very personal relationship with my fans and my close ones. Even when I meet people who appreciate my work, I talk to them as I talk to everyone else. That is the way I have always been, " she added.
