Helen Flanagan and Charlie Brooks will compete in the next Bushtucker Trial of I'm A Celebrity 2012, 'Come Dive With Me', it has been announced.
The underwater challenge involves a dining table with several sealed domes, which has been submerged in a pool of water. Each dome contains jungle critters, including lizards, spiders, crocodiles and crabs.
The soap actresses must swim beneath the table, push their heads in to each dome, and retrieve the stars inside using only their mouths.
A total of twelve stars will be available, each representing one meal for the campmates, who are about to be joined by two new contestants - 80s popstar Limahl and celebrity chef Rosemary Shrager.
Charlie has been nominated for the first time, while Helen is facing her fourth Trial, having taken part in every publicly-voted-for Trial so far.
I'm A Celebrity continues tomorrow night at 9.00pm on ITV1.
