Earlier, reports were doing the rounds that 36-year-old Zafar was replaced by Tahir Raj Bhasin in the movie amid row over banning Pakistani artists from working in India.
On being asked, the 23-year-old star said, "Nobody is being replaced. The film will release in its full form. There isn't much conversation happening around who's being replaced and who's not. So, we can leave the edge of that topic for sometime since it has died down."
The actress was speaking at the Absolut Elyx Filmfare Glamour and Style cover launch.
"'Dear Zindagi' is closest to my life. I am not saying I am exactly that character but I relate to it the most. Getting pissed off with relationships, there is a dialogue in teaser 3, where I say 'I hate couples'. That happens," Alia said.
