Alia Bhatt is doubling up as a singer again for her forthcoming film Humpty Sharma Ki Dulhania. Previously, the actress had received appreciation for her singing skills in Sooha Saha from Highway. After hearing her croon Samjhawan during the film's promotion, the makers decided to record the track with her. The new version, called Samjhawan Unplugged, will be released online this weekend.
