Irma was well-known for using reptiles in her acts and thought the king cobra, called Rianti, had been de-fanged. But when the snake bit her thigh, it injected venom into her bloodstream until a snake handler pulled it away.
'In the middle of the second song, Irma stepped on the snake’s tail. The snake then bit Irma in her thigh.'According to reports, the singer who had also used boa constrictors and pythons in previous acts, refused the offer of an antidote until she was done with her performance.
