Vidya Balan has apparently been approached once again by Rajnikanth to star in his next, despite turning down his offer last time

When Vidya Balan said no to Rajnikanth's Rana, everyone wondered why the actress would let go off such a golden opportunity, given the veteran South star's success rate at the box office.

However, that didn't deter Rajni from offering his next, Kochadaiyan to the actress. Buzz is that apart from Anushka Sharma and Asin, even Vidya has been approached to play one of the leading ladies in the film.

Says a source, "Like most people, Vidya too has immense respect for Rajni sir. Unfortunately, the last time she was approached for a role in his film, there wasn't a proper script in place. So she was not in a position to decide if she really wanted to take up the role, as the details were very sketchy. "

However, this time things seem to be looking up. Sources say that the actress has been given a proper character graph and everything that she would require to learn about the story and her role.

Adds the source, "Vidya is the flavour of the season. She has proven herself time and again and Soundarya (the producer) is looking for someone who can do complete justice to the part. Rajnikanth thinks she has great potential. "
