Collins dismissed her co-star's suggestion that he and Scott will continue a long-distance romance when they leave the jungle, claiming that the Australian model is actually "not his type".
"Mark and Emily aren't going to be together," Collins told The Sun. "She's not his type. She's got bigger boobs than Jessica-Jane Clement - that's why he's flirting with her. I know Emily used to be a poster girl on Mark's wall but he's just being a smoothie."
Wright's mother Carol has also cast doubt on the budding relationship, saying: "From what I've seen, I wouldn't call it a romance. They are more like friends."
Wright's TOWIE colleague and ex-fiancée Lauren Goodger last week predicted that he and Scott will soon break up.
"Mark is a very flirty boy anyway," she said. "That's just the way he is, it's quite funny... Mark gets bored easily, so it will be another one next week."
