Sanjay Leela Bhansali and Rani Mukherji, who shared a great friendship for years, have now totally stopped talking to each other.

It is believed that though Rani and Sanjay had a argument during the time the actor was shooting for Dil Bole Hadippa, the real reason for their fallout is Sanjay's decision to cast Aishwarya Rai Bachchan in Guzaarish.

A close source discloses, "Their relationship suffered a setback when Rani decided to do Dil Bole Hadippa. Rani is very close to Sanjay's sister Bela, who wanted to direct her in a film opposite Shahid Kapoor. Rani was reluctant because Shahid was younger to her. She backed out then but went on to sign the Yashraj film with Shahid. This annoyed both Bhansali and Bela."

The close hand further included, “Also, the title of movie (Hadippa) was Bela's intended title for her movie. Sanjay had mentioned to Rani to take up the matter with Aditya Chopra, but she didn't do much. In fact, some say that it was Rani who recommended the title."

It is common knowledge that Aishwarya, who is among Bhansali's favored heroines even after 2002, when she had fallout with Salman Khan, is making a comeback with Bhansali's next, Guzaarish, opposite Hrithik Roshan.

The close source told, "It is Rani's turn to feel bad because she's reportedly been telling people that Sanjay cast Aishwarya only because of the Dil Bole Hadippa episode. Rani has been among Sanjay's favourites as well, especially after Black."

Another close source tells, "We all know that Ash and Rani don't see eye to eye. So when Ash became the Bachchan bahu, her relationship with them also cooled off. Sanjay is neck deep in work and has no time for anything, while Rani has been overheard saying she doesn't want to be in touch with him anymore."
