"Imtiaz directing a music video with me for 'Highway', for the male version of 'Patakha guddi'. Do wait for ten days," Rahman posted along with a photograph on his Facebook page Sunday.
The photograph also features the film's leading lady, Alia Bhatt, and they are seen sitting in a truck.
The original "Patakha guddi" was the first song to be launched from the "Highway" soundtrack. Written by Irshad Kamil and sung by the Nooran sisters from Punjab, it is picturised on Alia.
The song's male version is likely to have been sung by Rahman, who has also crooned a romantic number "Maahi ve" for the movie.
"Highway", produced by Window Seat Films and presented by Sajid Nadiadwala, will be released worldwide by UTV Motion Pictures Feb 21. The music of the film will be available on T-Series.
