Kangana, along with her "Katti Batti` co-star Imran Khan, was present at a radio station here on Wednesday to promote their film.
On being asked how Salman convinced her to play the role of Payal in "Katti Batti", Kangana said: "He (Salman) didn't have to convince me... but he called me to tell me about the script of 'Katti Batti'.
"I'm glad that he did that because after 'Queen', I was flooded with offers for women-centric films, and I was giving them priority as well. I don't think I would have given it a thought."
She said that since Salman is her friend and she trusts him, "when he asked me to hear the script, I agreed. And after hearing the script in one second I said 'yes'."
In the film `Katti Batti`, Kangana will portray the character of a fun-loving, bold and open minded girl, but she insisted that her character Payal is different from Tanuja which she played in her last release "Tanu Weds Manu Returns`.
"Nobody is like Tanuja Trivedi in this whole world. Payal's is a different character, her life is not that exciting as Tanuja's. But yes, she is one of those people who I identify with.
"She looks very strong and bold from outside but from inside she is very soft and emotional. Payal is a very cute character but completely misunderstood," Kangana said.
Directed by Nikhil Advani, "Katti Batti" is set to release September 18.
