After making a successful debut as hero with Oru Kal Oru Kannadi, actor-producer Udhayanidhi Stalin is gearing up for the release of his next Neerparavai to be directed by Seenuramasamy. He recently signed his third film, which will go on floors in Jan 2013. This flick will be directed by N.R. Prabhakaran, who debuted with Sundara Pandian. Now the latest buzz is that the OKOK star has signed pretty lass Nayantara to play the leading lady. Interestingly, Udhayanidhi Stalin will once again team up with Santhaanam in this flick too. And we hear that he has also roped in Harris Jayaraj as the music director.
