Mumbai, Jan 30 (IANS): Bollywood's blockbuster director Rohit Shetty prefers to keep silent on rumours that he has managed a casting coup of Shah Rukh Khan and Kajol in his new film. He says he will reveal the details only next month.

"At this time, I guess everyone else apart from me is busy casting for my film and they are telling their own versions. I am just waiting for now and enjoying the process," Rohit said here when IANS asked the "Chennai Express" director to comment on the rumours.

By now, he's used to the "process".

"It's a process. Whenever I start a project, all this happens," he said, and added: "Next month we will let everyone know".

If the rumours turn out to be true, Shetty would have managed a lead cast that's been adored over the years in films like "Karan Arjun", "Dilwale Dulhania Le Jayenge", "Kabhi Khushi Kabhie Gham..." and "My Name Is Khan".

Meanwhile, Shetty is busy gearing up for another exciting project next month -- "Fear Factor: Khatron Ke Khiladi 6", which goes on air on Colors Feb 7 with 14 celebrity contestants.
