Sky One has ordered a second series of Celebrity Fear Factor for transmission this summer, C21 reports today.

Filming on the six episodes has already begun in Argentina, where celebs such as Charles and Diana Ingram, Sophie Anderton, Leilana Dowding, Lee Latchford-Evans, Terry Christian, Dane Bowers and Shane Lynch are facing the extreme challenges.

This time round said challenges will include sucking maggots from competitors' faces, bobbing for cow's eyeballs in a snake-filled vat of water and catching animal testicles with the mouth.

Celebrity Fear Factor begins Sunday, August 8, at 8pm and continues in that slot thereafter.
