Simbu Blackmailing Nayanthara?

The world knows about Simbu and Nayathara's affair in the past and they roamed openly like lovebirds and even had public smooches and kisses. Their affair went to the verge of a marriage before they broke-up. Now both are leading separate lives but Simbu has kept an eye on his ex girlfriend hoping that she might come back again. Nayan is not caring Simbu now hence Simbu is going to resort blackmail tactics , say Tamil industry sources . .
