"Last day of '2 States'! It's been beautiful and exciting. Will miss playing the Ananya Swaminathan. Too emotional today," Alia tweeted Sunday.
Dad Mahesh Bhat encouraged her by replying to her post: "My experience says that when the principal actor 'weeps' when a film is over, the maker smiles. This means your film is a hit."
"Well I hope I weep today then like I always do. Love you," posted the actress.
Directed by Abhishek Verman, the story is about a Punjabi boy who falls in love with a Tamil girl, and the ensuing cultural clashes between them and their families.
Alia will also be seen in Imtiaz Ali's "Highway".
