John Abraham and Aishwarya Rai [Images] fans will have to wait a little longer to watch them come together on screen.

It seems that the actress, who had given her nod to Sriram Raghavan's new film with John, is now delaying the shooting.

A source informs us that the shoot was to start by mid-January, but it had to be postponed because Ash did not allot her dates. The source also told us that John was very upset because of the delay, and even contemplated walking out of the project.

To make matters worse, his vacation with Bipasha Basu [Images] in Kenya also got cancelled because of the political turbulence in the country.

After the critical acclaim for his last film, Johnny Gaddar, Raghavan was gungho about his new film, and the casting coup. Let's hope his hopes aren't dashed.
