Kangana was reported to have been approached to play Dutt's wife Manyata in the film, which will see Ranbir Kapoor playing the titular role, but the 29-year-old National Award winning actress has rebuffed it saying she was never offered the film.
"Sanjay Dutt's biopic hasn't been offered to me but I am in talks with Raju sir for another project where I play a comedian," Kangana said in a statement.
Hirani's other film is a love story in which Kangana will be seen sharing screen with a known actor. Recently Hirani shot with Kangana for an advertisement with cricketers Virat Kohli and MS Dhoni.
