He describes the project as the "boldest and dirtiest" Indian film.
"Yes, we have approached Kim Kardashian and we know she is going through a special phase. We are ready to wait. I am very much sure Kim will easily connect with the idea of my film," Saif said.
Saif is confident that Kim will not turn down his offer.
Kim was supposed to visit India last year and also the sets of "Big Boss 8", but due to visa issues, her trip got cancelled.
"For Adults Only" is a trilingual to be made in Hindi, Tamil and Telugu. It will be produced by Dimension Films.
Saif plans to start shooting by September, and also hopes to rope in a popular Tamil actor to essay an important role.
