A source told a leading daily, "Kangna was fooling around the sets, showing off kicks learnt for her superhero film. One crew member challenged her to do a particular stunt. Though, Kangs wasn't in appropriate costume, she still tried it and fell down in the middle of the road. It was a bad fall and there was blood. The director and the crew got worried and called for a doctor."
The source further added,"However, Kangna who seemed in pain could not stop laughing at her own foolishness. Then the entire crew started laughing too. The film's director Vikas Bahl then apparently gave strict instructions to Kangs not to fool around on the sets anymore and she apologised for her childish behaviour and immediately returned to her shoot."
Well, Kangna there's a thin line between bravery and stupidity!
