"Aishwarya is a very respectable professional. It hurts to see how her sheer hard work is ridiculed to build one spicy story by the media. She has been a soft target.
And the sort of rumours rising now can damage my relationship with her. She has been my friend for a long time and I am afraid I will have a fallout with her, " Shah told over phone from Mumbai.
"There are certain people who are making systematic attempts to destroy my relationship with Aishwarya. There are gossip mongers who are spreading baseless rumours that she has refused to dub for 'Action Replay' after seeing the rushes. But none of this is true, " he added.
Shah gives three reasons to prove that all the rumours are baseless.
"Firstly, when the shooting of the film has not been completed, where's the question of the rushes and dubbing? Secondly, I haven't even seen the 'edit' of the film. After the shoot completes, it will take at least two and a half months to put it in order for a final cut; so there is no need for dubbing at the moment.
"And lastly, 'Action Replay' is in sync sound, so dubbing is totally out of the question. Besides, I have been busy for 'London Dreams'; Aishwarya has been busy shooting 'Ravana' and 'Guzaarish'. She has been travelling a lot so we didn't even have time to take 'Action Replay' forward. What is the logic behind these rumours then?" he added.
This apart, there were also rumours that Aishwarya had repeatedly rejected one of music composer Pritam Chakraborty's song for the film. But Shah denies it.
"It was I who had rejected Pritam's song thrice, not Aishwarya. The song was for her entry in the film and I wanted to crack a big song. I never allow my actors to my music recording studio - then from where have these rumours come out from?" he asked in an agitated tone.
Shah, who made hits like "Singh Is Kinng" and "Namastey London", is yet to shoot the last leg of the movie, which also features actor Akshay Kumar and Neha Dhupia.
"The last schedule of the film is still pending. We have planned to shoot it in December or January. Currently I am doing the recce for the locations, " he said.
