"It's a dream come true for me to be part of this film. I'm grateful to Karan Johar, Sajid Nadiadwala and Chetan Bhagat to have cast me in '2 States'," Arjun told reporters at the event.
Alia, who is riding high on the success of "Highway", said: "I was reading '2 States' while I was shooting for 'Student Of The Year'. I never thought a film will be made on this and I really liked the character of Ananya in the book. She is damn cool and I am happy to do this film."
The movie will release April 18.
