Australian Tv star Hamish Blake has been hospitalised in South America after a Tv stunt involving stinging ants went wrong.

The radio and Tv funnyman has been in Argentina and Brazil filming the latest series of his comedy travel show Hamish and Andy's Gap Year South America with his partner Andy Lee.

However, filming of the programme's finale came to a halt after Blake took part in an Amazonian ritual involving bullet ants, which give a nasty sting. He was admitted to a hospital in Manaus, Brazil which specialises in tropical diseases, and was treated for the ant bites and exhaustion.

Blake posted pictures of his swollen hands on his page along with the caption, "24 hours after the bullet ants I still gave them exactly no thumbs up (even if I could move my thumbs). On the plus side, no danger of wedding ring slipping off!"
