In the song, titled 'Sacchi Mohabbat', Pannu and her co-star Abhishek Bachchan are seen standing next to each other. Midway into the song, yet another still from the movie appears, featuring Vicky Kaushal and Pannu.
The 'Pink' star took to her Twitter handle, writing, "My favourite ! #SacchiMohabbat lyrical video out now."
The song talks about complexities of love and how conversations between lovers about moments are often found and lost.
Sung by Shahid Mallya and Jonita Gandhi, the new song has been composed by Amit Trivedi and the lyrics have been penned by Shellee.
'Manmarziyaan' will see Bachchan return to the big screen after a gap of two years as he was last seen in the 2016 rom-com 'Housefull 3'.
The film also stars 'Sanju' fame Vicky Kaushal in a pivotal role.
Directed by Anurag Kashyap, the flick will hit the big screens on September 14 this year.
