First Class: Alia Bhatt and Varun Dhawan match steps at Kalank song launch

Varun Dhawan and Alia Bhatt are back! The hit on-screen jodi is reuniting for Karan Johar's Kalank, and the two launched the song First Class.

But this song launch had a twist. Alia and Varun unveiled the song at Mumbai's Gaiety Cinema.

Clad in a black salwar kameez, Alia looked pretty as she matched steps with Varun on the song.

Kalank is Alia and Varun's fourth collaboration after Student Of The Year, Humpty Sharma Ki Dulhania and Badrinath Ki Dulhania.

Interestingly, First Class has Kiara Advani and Varun Dhawan. But it was Alia Bhatt who released the song along with her co-actor.

Kalank which also stars Madhuri Dixit, Sanjay Dutt, Sonakshi Sinha and Aditya Roy Kapur is set to hit the screens on April 17.
