Aishwarya Rai Bachchan's dates have become a big issue.

She and her husband Abhishek Bachchan had cancelled their shooting for Mani Ratnam's film 'Raavan' owing to the illness of megastar Amitabh Bachchan on his birthday, last month. The shooting of the film had to be completely rescheduled.

But the juggling act of the busy actress is now making things a little difficult for director Shankar. This in spite of Ash working with him in one of her earlier films 'Jeans' years ago.

Sources say, "Endhiran, which stars Ash opposite Rajinikanth, has been forced to call off a shoot as Ash was busy shooting for Mani along with her hubby. S Shankar had scheduled a shooting stint at Kulu Manali, which was to start on November 14.

He wanted to shoot a few sequences with his leading stars in this valley but had to change his plans. While southern superstar, Rajini, was available, Ash was still holed up in Kochi shooting for Mani's film."

The buzz is that the director has now decided to shift his shooting to Chennai, where he will shoot all the portions that just require Rajinikanth. He's trying to quickly wrap up the sequences with the Southern superstar and then will have another schedule, where he hopes to finish the Ash- Rajini sequences.

Well, we can only say that working with a busy actress has its highs and lows!
