Looks like someone is working very hard! Karan Johar's discovery and Mahesh Bhatt's daughter Alia Bhatt fainted on the sets of Jhalak Dikhhla Jaa, while promoting her upcoming film. Alia Bhatt was with the two lead actors of her upcoming film Sidharth Malhotra and Varun Dhawan on the show, which incidentally is judged by her film's director Karan Johar.

The debutante was performing to the song Disco Deewane from her upcoming movie, when she fainted. A source from the units said, "The shoot took place in the night around 10 and she fainted there, resulting in complete chaos on the sets." The source also added that it was a high-energy dance act that led to Alia losing her consciousness. "There were lot of swirls and twirls.

Remo, who is also a judge on the show, wanted to make sure that the act is high voltage. At the end of the act, she missed her balance but somehow managed to get herself back on her feet. However soon after, she collapsed," the source said. Karan Johar apparently rushed to his heroine's aid and the shoot was stalled for nearly one hour. "Karan was extremely concerned and made sure that Alia was fine before the shoot resumed," the source said.
