The Only Way Is Essex star was teased by the model after his successful Pits of Peril bushtucker trial.
She told him: "I promise I won't look at your mealworm but what if I drop the towel?"
"I will throw you in," replied Mark before Emily retorted: "Then it will be worth it."
Explaining how the situation developed, Wright said suggestively: "Emily is the camp bike so must come with me to the shower.
"She is going to see loads of mealworms floating about but she can see my mealworm because it's cold in that pond and it does turn into a mealworm. I've got no shame because I stink and I need to wash and I'm getting in butt naked."
Speaking to Jessica-Jane Clement, she said of Wright: "I like his chest. He's a good looking boy with a nice smile. We've been having fun and we're a bit flirty and cheeky so who knows where that will go."
