"When Honey Singh was shooting for the last bit of the first episode, an unforeseen incident happened with him. He slipped and fell down," said a source close to the show's production house.
"He faced minor bruises but his spirit was undeterred. He immediately got up and to everyone's surprise, created no fuss and agreed to re-shoot," the source added.
On "India's Raw Star", Honey Singh will be seen as a friend, mentor and guide to the contestants.
The show, where singers from across India will battle it out to bag India's Raw Star title, will be hosted by model-actress Gauahar Khan.
It will go on air on Star Plus Sunday.
