The Udta Punjab star will be seen in a cameo in the romantic-drama. This is the second time she has worked in a KJo-directed project, after her debut film Student Of The Year.
When asked about her role, Alia told reporters, "I've already been that (DJ, in the film). I hope it feels better to watch on screen. It was a very nice experience getting to work second time with Karan. It was really good."
The actress added: "Watch the cameo in the film. It is very good."
Ae Dil Hai Mushkil stars Ranbir Kapoor, Aishwarya Rai Bachchan and Anushka Sharma in lead roles. It also features Pakistani actor Fawad Khan in a special appearance. There will also be a Shah Rukh Khan cameo in the film.
Alia was speaking at the Filmfare Glamour and Style Awards in Mumbai.
The actress said she considers Amitabh Bachchan and actress Kangana Ranaut to be very fashion forward.
"I think Mr Bachchan is very glamorous. He is very classily glamorous. And I feel Kangana Ranaut is very glamorous too," she said.
Alia, meanwhile, will be next seen in Dear Zindagi and Badrinath Ki Dulhaniya, which stars Varun Dhawan.
