Varun Dhawan is slowly turning into a complete entertaining package. Reportedly, the actor was spotted outside Yash Raj Films studio, where he is recording a song for his upcoming film 'Humpty Sharma Ki Dulhania'. According to sources, Varun was singing with Shreya Ghoshal and left everyone impressed with his skills. The actor seemed to have got his notes right and in sync. Varun was much praised for his acting in recent success 'Main Tera Hero'. Hopefully his singing will do well too. 'Humpty Sharma Ki Dulhania' stars Alia Bhatt opposite Varun.
