As part of this week's Against All Odds shopping challenge, Rylan was tasked with eating his way through a box of chocolates, avoiding ones that had been secretly filled with scotch bonnet chillies.
If Rylan managed to find all the real chocolates, he would win the house 20 Pass balls for the overall weekly task.
However, the wannabe celebrity stumbled upon 4 hot spicy chocolates during his mission and ended up vomiting in a sick bucket because of the intense heat.
Rylan's task will be shown on this evening's show.
Claire Richards was also set an endurance task yesterday and was forced to listen to her pop group Steps' number one hit '5, 6, 7, 8' on repeat in a private room.
