Actress Vidya Balan ’s Kahaani 2 avatar and the gripping trailer has become the talk of the town. Fans are eagerly waiting for the film to be out in theatres. The latest news from the sets of the movie is that, Vidya apparently broke down after watching child artist Naisha perform a nerve wrecking stunt.

Naisha had to jump down the roof top for a scene and though it was performed with all the safety measures and under expert supervision, Vidya got so scared that she started crying, according to the sources.

In a statement, Vidya Balan stated that, "Naisha is such a strong and brave girl. I was surprised to see the ease with which she executed the stunt. It gave me knots in the stomach and I started crying. Naisha, on the other hand, smiled at me as if nothing happened."

Writer-director Sujoy Ghosh adds, "Vidya is a big prankster on the sets, always on the lookout for her next target. So, when we saw her crying, we took it to be one of her pranks. After sometime, however, we realised that she was not faking it. It took me at least two hours to pacify her."
