In the worrying scenes, Ben wore nothing but a black leather jockstrap, a mankini with a pompom on the crotch and a g-string that revealed the extent of his manscaping.
While Ben seemed completely at ease with his state of undress on camera, Christie was less than impressed.
“No! Get it off, you creep!” she said.
This isn't the first time Christie has been shocked by Ben in their relationship.
The dating project manager told New Idea that when it came to going on the show, Ben completely blindsided her.
“He actually applied by himself, I had no idea,” she said.
“He applied for it and got through the first few rounds of casting and then he goes, ‘by the way I’ve applied for this show’.”
Christie was completely taken aback by his decision.
“I was just like, ‘What have you done?’” she recalls.
“I didn’t know anything about it, so I was a bit overwhelmed, but at the same time it was kind of exciting.”
