With Asin, having set a strong foothold in Bollywood with Ghajini, Trisha doing Khatta Meeta opposite Akshay Kumar under Priyadarshan's direction, and Nayanthara trying to move to Bollywood - of course after her Tamil film Aadhavan and a couple of Telugu films to complete - the only heroine that is ruling the roost now in Kollywood is Tamanna, Tamil film industry sources feel. Apart from having a number of films with top heroes like Vijay and Karthi, Tamanna is also considered to be a lucky charm for producers looking for box office moolah because all her recent films have been smash hits.
