A jay Devgan literally shocked Vidya Balan on the sets of Halla Bol recently. Vidya reveals, "We were shooting for Halla Bol and I was busy discussing my scene with director Rajkumar Santoshi. Ajay came to us and started discussing the new song he had record ed for the film.

They started praising it to the skies and Ajay noticed the excitement on my face for I was very eager to hear the number and Ajay immediately took out his iPod and the headphones from his pocket and offered it to me so that I could hear the number." She adds, "So soon I pressed the play button, I immediately felt a mild shock! I noticed the entire unit laughing at me along with Rajkumar. I was so embarrassed." That's Ajay for you.
