Why is Aishwarya Rai fuming at Katrina Kaif?

A little birdie tells us that after the rumour that Katrina Kaif walked out of The Italian Job because she didn't want to be paired with Abhishek Bachchan reached Jalsa, Aishwarya Rai has been fuming.

It is learnt that she has told her hubby he should do the same and not work with her in Dostana 2.

A source reveals, "Ash is happy that the project has been postponed. Now that Kat's dates have gone for a toss with the film not taking off until mid 2011, Ash is hoping that some one else might step in." We hope it is Ash herself.
After all she was the first choice for the original.
