According to sources, while shooting for the film SAAT KHOON MAAF, Priyanka was required to scream at the top of her voice for a particular sequence. Following Vishal Bharadwaj's instructions, Priyanka started doing the same only to find out that she had stretched her vocal chords to a point where she couldn't scream or even talk anymore.
Now, Priyanka is mute these days. The actress has been advised rest by doctors till she regains her voice.
