It's almost a decade of films for hottie Nayantara who is sizzling in almost all the three major tinsel towns of South India. And she's opening her voice for the first time now. Nope, she isn't talking about her affair with director Vignesh Shivan or any other controversial stuff. Though Nayan is a Malayali girl, she is quite fluent in Tamil and for that reason she is dubbing herself for her role in "Naanuam Rowdy Dhaan", directed by her rumoured beau Vignesh Shivan. A look at the trailer of the movie has stunned many industry biggies as they could hear Nayan' voice. After coming to known that she dubbed herself, then everyone stunned.Probably Nayan took a cue from her junior Nitya Menon who is already rocking with own voice.
