Actor Alfonso Ribeiro broke down in tears within hours of beginning his stint on jungle-based reality Tv show I'm a celebrity... Get Me Out Of Here! when he was forced to confront deadly scorpions and leap from a helicopter.
The Fresh Prince of Bel-Air star has joined contestants on the British Tv hit, in which celebrities face their biggest fears while spending three weeks camping in an Australian rainforest.
The 2013 series of the endurance contest launched on Sunday (17Nov13) and Ribeiro's nerves began to show within minutes.
He was seen trembling with fear and saying he was "really, really nervous" as he prepared for the contestants' traditional skydive into the jungle and admitted after landing safely that it had been "quite possibly the scariest thing I've ever done in my life," adding, "I didn't like that."
However, his first day in the camp went from bad to worse when he took part in a trial to win food for his teammates and had to solve a puzzle while 75 scorpions crawled over his head, face and body.
After winning the task, Ribeiro was seen wiping tears from his eyes and fighting to control his emotions as he said, "That was, er... tougher than I thought."
Former Westlife singer Kian Egan reportedly received treatment from medics for several cuts to his body he suffered while racing his rivals across an island at the start of the contest.
Other stars taking part in this year's (13) U.K. series include six-times world snooker champion Steve Davis and Olympic gold medal-winning swimmer Rebecca Adlington.
