Alia Bhatt faints on sets of 'Jhalak Dikhhla Jaa'

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 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. Alia fainted at the end of her act where she performed on the song Disco deewane. A source from the units says, "The shoot took place in the night around 10 and she fainted there, resulting in complete chaos on the sets."

The source suggests 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," adds the source.

Karan 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," concludes the source. Karan Johar and Alia Bhatt remained unavailable for comment.u00a0
