The movie is titled "Paris Paris".
Aggarwal, 32, who is looking forward to the film, said it will be adapted to suit the sensibilities of the Tamil audiences.
"This project is very dear to my heart... I can't be grateful enough for having a team on board which is extremely enthusiastic, very like-minded and as excited as I am or even more, for the project which is utmost challenging," Kajal told reporters at the film's launch event here.
Asked about how she is going to handle the comparisons with Kangana, Aggarwal said, "I'm not here to fill in anyone's shoes but I am going to do it my way and I am going to treat this as an original script.
