Nisha Kothari has fallen out with her mentor Ram Gopal Varma according to the B-town buzz.

Apparently she is upset with Ramu since he has been promoting his latest protégée, Jiah Khan, much more than her. He is so enamoured with Jiah that one of his future projects, starring Kothari, is now in the Nishabd actress's kitty.

Even though Nisha play's a part in RGV's Sholay, things have turned sour between Ramu and her.

A lead role for one of his upcoming films was written specifically keeping Nisha in mind, but now that same role is being reworked for Jiah," says a source close to the Factory.

It is reported that Jiah is in talks for another project with Ramu, but is not willing to say whether she's taken over Nisha's role in the untitled project.

Ramu insists this is not true, sources from the sets of RGV's Sholay confirm that as a result of his problems with Nisha, he has now shot a song with Sushmita Sen.

It is also learnt that Nisha is unhappy with the way her role in Sholay is shaping up.

"She wants to do a variety of roles and does not want to get typecast as the pretty girl next door. In fact, Nisha is now sending signals to loads of filmmakers to get interesting roles," says a friend close to her.
