Alia Bhatt and Varun Dhawan singing 'Humsafar' song from 'Badrinath Ki Dulhania' is a must watch!

New Delhi: Our Bollywood stars are coming up with innovative ways for promoting their upcoming ventures. And not just films but even song releases. Yes! Alia Bhatt and Varun Dhawan starrer 'Badrinath Ki Dulhania' will be out in the theatres on March 10, 2017, and the promotional gig is already in place.

One of the latest songs from the film 'Humsafar' will be releasing today in the afternoon but that has not stopped the makers from teasing a few lines in advance. And what better way that making your lead stars sing it along.

Alia, who is a good singer, by the way, took to Twitter and shared a small video singing a few lines from the unreleased number 'Humsafar', challenging her Badri aka Varun to sing the next two lines. To which Varun happily replied with humming the lines of 'Humsafar'.
