Megastar Amitabh Bachchan and son Abhishek have expressed grief over the death of child artist Taruni Sachdev, their co-star in the film Paa. Taruni was among 13 Indians who were killed in the Nepal plane crash. The aircraft crashed into a hill while coming in to land at Jomsom in western Nepal. “Just reading that Tarini Sachdev the girl child artist in Paa, has perished in Nepal plane crash... please God may this not be true,” Amitabh tweeted. Taruni, 14, was famously known as the Rasna girl because of her appearance in the soft drink ad. She had featured in almost 50 ads with Bollywood stars including Karisma Kapoor. “SHOCKED and very saddened to hear about the Nepal plane crash. Lost 1 of my cutest co-stars. Little Taruni Sachdev from PAA. Speechless,” Abhishek posted on his Twitter page.
