Taalash has been delayed, prompting rumours that the film is too similar to the thriller starring Vidya Balan.
She told Hindustan Times: "Such things happen. A film getting delayed is not uncommon. The film is ready and the first edit is also in place. I am not bothered that the film will arrive a few months later. I am chilled out.
"Let Talaash release and the film will speak for itself. People will realise on their own that there is no similarity whatsoever."
The thriller, which sees Khan playing a cop, is his first film since the release of 3 Idiots three years ago.
Khan is also shooting his television show Satyameva Jayate, which documents the lives of everyday people in India.
He admitted that he had forced himself to go offline in order to concentrate wholly on making the show.
The actor-turned-producer has described it as his most ambitious project yet.
