Nayantara didn't create any sensation with blockbuster films Chandramukhi, Ghajani and Lakshmi but her Billa is doing that! Billa is much talked about only for the skin show of Nayantara in which she outperformed the sexy damsel Namita too! For the first time in her career Nayantara appeared in a two piece bikini and that scene was the highlight of Billa, her fans say.

With the bikini show becoming popular the makers of Billa are thinking on making money on it. The bikini wore by Nayantara is going to be auctioned as per Tamil media and let's see who is the lucky one that is going to own this. One can expect that the auction price would definitely be in lakhs, after all it is the craziest bikini around.
