That is true. Bindu was Amitaabh's friend. When she hears Jaya sing for the first time, she tells her that at first she was hurt,when she heard that Amitabh-whatever his name was in the movie-has married someone else, but after hearing her singing,she thinks that Uma(Jaya) is right for him-or something of this kind. So she did not act as vamp. & I liked her role too.
well, Mallika wasn't exactly a vamp either!!! 😕
