The actor, who was last seen in Argentina Fans Kaattoorkadavu, made her debut alongside Nivin Pauly in Njandukalude Nattil Oridavela. Though the production house of the film, Y Not Studios is remaining tight-lipped about the news, sources state that it's certain that the actor will be playing the female lead. 

Aishwarya is currently working on her first Tamil film directed by Sundar C, co-starring Vishal and Tamannaah. She also recently finished shooting for Prithiviraj's Brother's Day. 

The news about Dhanush-Karthik Subbaraj project has been doing rounds for more than two years and it was put on hold for the director to work on Rajinikanth's Petta.
